Replacing a honda pilot fuel injector can be confusing because the correct part depends heavily on the Pilot’s model year, engine, connector, and original-equipment number. A complete set may also be a better choice than replacing only one injector when several cylinders show similar symptoms, but fitment should come before price or hole count.
My first choice is SCITOO 6 Holes 6pcs Fuel Injectors. It covers the newer Pilot applications in this comparison, includes six injectors with O-rings, and uses a multi-hole nozzle design intended to support consistent atomization. Bench testing before shipping and a direct-fit design make it a practical starting point for a full-set replacement.
My second choice is Gledewen Gledewen Fuel Injectors 6 PCS. My alternative is the Gledewen 6-Piece Fuel Injector Set for 2003-2017 Honda Accord, Odyssey, Pilot, and Ridgeline applications. Its broad vehicle coverage and 24-month replacement-or-refund warranty may appeal to owners of older Pilots who want a clearly stated support policy, provided the listed reference number matches the original injector.
This comparison ranks five complete injector sets, then explains how fitment, injector design, sealing parts, testing claims, warranty coverage, and installation details affect the buying decision. The guide also covers compatibility checks, installation preparation, maintenance, troubleshooting, common mistakes, and questions owners often ask before ordering.

SCITOO 6 Holes 6pcs Fuel Injectors
SCITOO earns the top position because it is specifically listed for the 2016-2020 Honda Pilot with the 3.5-liter engine, which makes its intended application easy to identify. The six-piece set is appropriate when replacing the injectors across the entire engine rather than mixing an old injector with several new ones. It is also listed for select Odyssey and Ridgeline models, but the Pilot year and engine should remain the deciding factors.
The multi-hole nozzle design is intended to improve fuel atomization, which can support smoother combustion and throttle response when the injectors are properly matched to the vehicle. A hardened steel body and precision-machined components are described as durability-focused choices, while the metal-composite-plastic construction keeps the design aligned with common modern injector materials.
Installation should be relatively direct because the injectors are designed to fit the factory fuel rail and intake manifold without modifications. O-rings are included, and the seller states that each injector is bench-tested before shipment. Those details reduce the need to source sealing parts separately, although careful inspection of every O-ring is still important before pressurizing the fuel system.
Pros
- Specific coverage for Honda Pilot 3.5L models from 2016 through 2020
- Complete six-injector set with O-rings included
- Bench-tested before shipping according to the product information
- Two reference numbers are provided for fitment comparison
Cons
- Not intended for every Pilot model year
- Fitment should be confirmed against the original injector and vehicle details
My Opinion
This is the strongest all-around option in the group for a 2016-2020 Pilot 3.5L owner who wants a complete, direct-fit set. Its newer-Pilot coverage and included sealing parts give it an advantage over the older-application choices, but it should not be ordered for an earlier Pilot simply because the engine displacement is also 3.5 liters.
Gledewen Gledewen Fuel Injectors 6 PCS
The Gledewen set stands out for its unusually broad stated coverage. It is listed for Honda Accord, Odyssey, Pilot, and Ridgeline models from various years, along with several Acura and Saturn applications. For a Pilot owner, that broad range can be useful when researching an older vehicle, but it also creates a greater need to verify the exact year, engine, connector, and original-equipment number before purchase.
Gledewen describes the injector as providing a stronger injection capacity and a smoother atomized spray. In practical terms, that positioning is aimed at helping fuel reach the combustion chamber consistently, which may be useful when worn or poorly functioning injectors contribute to rough running, hesitation, or an uneven idle. These are product claims, not a guarantee that every drivability problem will be corrected by injector replacement.
The long list of replacement numbers is one of this set’s most useful features. Numbers such as 16450-RCA-A01, 16450-RGL-A01, FJ485, and several aftermarket references give buyers more ways to compare the listing with the number on the removed part. The stated 24-month warranty also provides a stronger support window than many replacement parts, especially for owners who are cautious about purchasing a non-original component.
Pros
- Broad coverage for many 2003-2017 Honda Pilot applications
- Several original-equipment and aftermarket reference numbers are listed
- 24-month replacement-or-refund warranty is stated
- Six-piece set suits a complete injector replacement
Cons
- Wide fitment range makes detailed compatibility checking essential
- The listed applications do not cover every Pilot generation equally
My Opinion
This is the best alternative for an older Pilot owner whose original injector number matches the listing. Its warranty and reference-number coverage are appealing, but the broad application list should be treated as a starting point rather than automatic proof of compatibility.
Frezon 6-Piece Fuel Injectors
Frezon targets the same newer Honda application as several other entries here: the 2016-2020 Pilot 3.5L, along with select 2018-2019 Odyssey and 2017-2019 Ridgeline models. The listing specifically references 16010-RLV-305 and 16010-RLV-315, making this set worth considering when one of those numbers matches the injector being replaced.
Its strongest technical selling point is flow matching. The product information says each injector is checked so the set can deliver consistent amounts of atomized fuel to the engine’s cylinders. That matters because a complete set with similar flow behavior is preferable to installing a mixture of injectors with unknown wear or substantially different delivery characteristics.
Frezon also lists pressure, leak, spray, and flow testing, along with matching internal coil resistance and fuel-flow rate to the stated original-equipment injector characteristics. These checks are useful on paper because leakage and inconsistent flow can cause hard starts, poor idle quality, or fuel-related fault symptoms. Still, the listing does not provide individual test sheets or measured values for the specific set shipped to a buyer.
The direct-fit design is intended to avoid modifications, and the seller says quality checks occur throughout production as well as before shipping. Buyers should still compare the connector and body shape before installation, because a direct-replacement claim cannot overcome an incorrect year or reference number.
Pros
- Fits listed 2016-2020 Honda Pilot 3.5L applications
- Flow-matching and leak-testing claims address important injector concerns
- References both 16010-RLV-305 and 16010-RLV-315
- Designed as a direct replacement
Cons
- Available customer-feedback volume is limited
- Testing claims are not accompanied by individual measurement reports
My Opinion
Frezon is a sensible second-tier choice for a newer Pilot when flow consistency and multiple stated quality checks matter most. Its lower position reflects less available customer-feedback evidence than the top options, not a missing feature that automatically disqualifies the set.
SeyPon Set of 6 GDI Fuel Injectors
SeyPon offers another newer-generation option for the 2016-2020 Honda Pilot 3.5L, with additional coverage for the 2018-2019 Odyssey and 2017-2019 Ridgeline. The listing identifies the product as a set of six GDI injectors and provides the same two key reference numbers used by several newer-application parts: 16010RLV305 and 16010RLV315.
Its fuel-economy emphasis comes from the injector’s ability to control the amount of fuel delivered to the engine. Accurate metering is important because too much or too little fuel can affect combustion quality, but buyers should keep expectations realistic: replacing a faulty injector may restore normal operation, while it cannot guarantee a specific fuel-saving percentage if the vehicle has other problems.
SeyPon also emphasizes precision manufacturing, quality control, and long-term durability. The maintenance guidance in the listing suggests cleaning at roughly 40,000-60,000 kilometers when the vehicle and fuel quality are good. That interval is not a universal Honda requirement, so it is better used as general seller guidance rather than a substitute for diagnosis or the vehicle’s maintenance information.
The Amazon vehicle-fit confirmation tool is specifically recommended before ordering. That is particularly important here because the set is designed for a narrow group of newer Honda 3.5-liter vehicles, not every Pilot. The seller also states that its support team aims to respond within eight hours, which may be helpful if an installation or fitment question arises.
Pros
- Clear coverage for Pilot 3.5L models from 2016 through 2020
- Six-piece set with both listed newer-Honda reference numbers
- Seller provides an explicit cleaning interval as general guidance
- After-sales response commitment is stated
Cons
- Only two customer ratings are available in the supplied data
- Fuel-economy benefits should not be treated as guaranteed results
My Opinion
SeyPon is a reasonable fitment-focused option for a newer Pilot owner who values seller communication and a clearly stated application list. I would place it behind SCITOO and Frezon because the available customer-feedback evidence is very small, making compatibility verification especially important.
oktiger 8-Hole Fuel Injectors
oktiger is the oldest-application choice in this comparison. Its six-piece set is listed for Honda Pilot 3.5L models from 2005 through 2011, as well as several Odyssey, Ridgeline, Accord, Acura, and Saturn vehicles. That makes it unsuitable for a 2016 or newer Pilot, but potentially relevant to owners of the earlier Pilot generation whose original injector number matches.
The eight-hole design is intended to create a fine fuel mist for combustion, while the listed specifications identify a gas application, male blade-style terminals, two terminals, and preinstalled O-rings. The inclusion of sealing rings simplifies preparation, but preinstalled parts should be checked for cuts, twisting, dirt, or flattening before the injector enters the rail.
oktiger states a flow tolerance of plus or minus 2 percent and describes precision-machined spray holes and a high-carbon chromium stainless-steel construction. It also claims improved fuel efficiency and throttle response. Those are ambitious performance statements, so buyers should view them as manufacturer claims rather than guaranteed outcomes, particularly when an older engine may have ignition, vacuum, compression, or fuel-pressure issues.
The one-year warranty and stated response time of 24 hours add useful ownership support. The large application range makes this a product for careful part-number matching, not casual year-and-engine matching alone. Comparing the original injector, connector, and reference number before removing the old parts can prevent an otherwise avoidable return.
Pros
- Specific coverage for 2005-2011 Honda Pilot 3.5L models
- Six injectors with O-rings listed as preinstalled
- Eight-hole design and stated flow-tolerance specification
- One-year warranty with replacement-or-refund support
Cons
- Does not fit the newer Pilot applications ranked above it
- Some performance claims are not independently documented in the supplied data
My Opinion
This is the most relevant choice here for an early Pilot owner who needs the 16450-RCA-A01 or related application. It ranks fifth only because its fitment is limited to older vehicles and its broader claims should be weighed less heavily than a confirmed part-number match.
How I Selected These Honda Pilot Injector Options
The ranking favors products that make the application, quantity, reference numbers, and installation requirements reasonably clear. I also considered whether the set is aimed at the newer 2016-2020 Pilot or earlier 2005-2011 and 2003-2017 applications, because a technically attractive injector is still the wrong purchase if the connector or fuel system does not match.
Product-specific testing claims were treated as stated seller information, not as independently verified results. Where customer-feedback evidence was available, it was considered as context, but the supplied data does not establish long-term durability for any option.
Fitment evidence matters more than hole count, advertised fuel savings, or a high rating based on only a few customer responses.
The first two positions went to options with useful combinations of application clarity, complete six-piece coverage, included sealing parts or reference numbers, and practical ownership support. The remaining products still have legitimate use cases, especially when their listed part numbers match the vehicle’s original injectors.
How to Choose a Honda Pilot Fuel Injector
Start with the vehicle identification label, model year, engine, and the number printed on the original injector or the vehicle’s parts record. Then compare the connector shape, terminal arrangement, body design, and included seals before considering design claims such as six-hole or eight-hole spray patterns.
- Match the model year: A 2005-2011 Pilot application is not interchangeable merely because both engines are 3.5 liters.
- Confirm the reference number: Compare numbers such as 16010-RLV-305, 16010-RLV-315, or 16450-RCA-A01 with the removed part.
- Buy the correct quantity: A six-cylinder engine generally benefits from a matched six-piece set when replacing all injectors.
- Check the seals: O-rings included in the package reduce extra parts shopping, but they still need inspection before use.
- Use seller support wisely: A warranty is valuable, but it does not replace checking compatibility before installation.
Why the original injector number matters
Aftermarket catalog descriptions often cover several Honda, Acura, and other vehicles. That broad compatibility language can be helpful for research, but it can also hide small differences in fuel-rail fit, electrical connection, flow behavior, or sealing dimensions. The number on the original unit is one of the fastest ways to narrow the search.
When replacing one injector makes sense
A single replacement may be appropriate when diagnosis clearly identifies one failed injector and the other five have known condition and matching specifications. A complete set is more logical when several injectors are worn, the engine has high mileage, or the existing units have unknown history, but the added cost and installation time should be considered.
Check Compatibility Before Ordering
Before buying, enter the exact vehicle into the marketplace fitment checker when available, then compare the listing with a second source such as the owner’s manual, a trusted parts catalog, or the number stamped on the existing injector. Do not rely on a generic phrase such as “fits Honda 3.5L.”
- Verify the Pilot’s model year and engine size.
- Confirm whether the injector is intended for the vehicle’s fuel system.
- Compare electrical terminals and connector orientation.
- Check the original-equipment number against every number in the listing.
- Make sure all six injectors are included if a complete replacement is planned.
Prepare for Installation
Fuel-system work should begin with the engine completely cool and the vehicle parked on a stable surface. Relieve fuel pressure according to the vehicle’s service procedure, disconnect the battery when appropriate, and keep ignition sources away from spilled fuel.
Have clean rags, suitable eye protection, replacement seals if the package seals appear damaged, and a way to protect open fuel-rail and intake ports from dirt. Photographing connector locations before removal can help prevent crossed connections during reassembly.
Basic installation sequence
- Confirm that the replacement injector shape and connector match the removed unit.
- Relieve fuel pressure and disconnect the electrical connectors carefully.
- Remove the rail and old injectors according to the vehicle service instructions.
- Lubricate compatible new O-rings lightly as directed by the service information.
- Seat each injector evenly without forcing or twisting the seal.
- Reassemble the rail, reconnect the wiring, and inspect the area before starting.
- Cycle the ignition as appropriate and check carefully for fuel leaks.
Inspect O-Rings and Seals Carefully
An injector can have the correct electrical specifications and still cause trouble if an O-ring is cut, pinched, dry, or improperly seated. A leaking seal can create a fuel hazard, introduce an air leak, or prevent the injector from sitting squarely in the rail.
Included O-rings are convenient, but “included” does not mean “install without inspection.” Keep the sealing surfaces clean, avoid metal tools that can gouge the injector or rail, and replace any seal that looks flattened or damaged.
Prime and Check the Fuel System
After installation, do not immediately drive away. Reconnect the necessary components, turn the ignition on and off as appropriate to build pressure, and inspect the rail and injector bases for wetness or fuel odor before starting the engine.
Once the engine runs, allow it to idle while checking again. A rough idle, hard starting, fuel smell, or visible leak requires shutting the engine off and diagnosing the problem rather than assuming the injectors simply need more driving time.
Symptoms That May Point to an Injector Problem
Possible injector-related symptoms include a rough idle, hesitation, misfire, difficult starting, poor acceleration, or an engine warning light. These signs are not exclusive to injectors; spark plugs, ignition coils, vacuum leaks, fuel pressure, sensors, and engine compression can create similar behavior.
Diagnosis should therefore come before ordering a complete set. A fault code can identify a cylinder or circuit, but it does not always prove that the injector itself is the failed component.
After installation
- Check for leaks before driving.
- Confirm that every electrical connector is fully seated.
- Look for a persistent misfire or warning light.
- Monitor starting quality and idle stability.
- Recheck the installation if symptoms began immediately afterward.
Maintenance and Injector Cleaning
Routine fuel-system maintenance cannot repair an electrically failed injector or a damaged seal, but clean fuel and timely attention to drivability symptoms may help prevent small problems from becoming larger ones. Use fuel from reputable sources and follow the vehicle manufacturer’s maintenance guidance rather than relying on a universal cleaning schedule.
SeyPon suggests cleaning at 40,000-60,000 kilometers under favorable operating conditions, but that interval is seller guidance and should not be treated as a mandatory rule for every Pilot. Professional off-car cleaning may be useful when clogging is suspected, while a fuel additive should never be used as a substitute for diagnosing a misfire or leak.
Common Mistakes to Avoid
Most injector replacement problems begin with incorrect fitment, rushed preparation, or a failure to check for leaks. Avoiding these mistakes is more valuable than choosing a part based only on the largest number of spray holes or the strongest performance wording.
- Ordering by engine size alone instead of matching year and reference number
- Mixing old and replacement injectors with unknown flow characteristics
- Reusing damaged, flattened, or dry O-rings
- Installing parts while the engine or fuel system is still hot
- Forcing an injector into the rail when the seal does not seat easily
- Skipping a leak check after reassembly
- Assuming every misfire is caused by the injector
Never drive a vehicle that has a fuel leak, strong fuel odor, or an unresolved injector connection problem.
When Should You Replace the Injectors?
Replacement is usually considered when diagnosis confirms an injector that is leaking, electrically open, clogged beyond practical cleaning, or delivering fuel inconsistently. A set may also be selected when multiple injectors show similar wear, but replacing all six is not automatically required for every isolated fault.
Keep the removed injectors until the vehicle runs correctly and there are no leaks. If a problem remains, the original parts can help with comparison, warranty communication, or further diagnosis.
FAQS About Honda Pilot Fuel Injector
How many injectors does a Honda Pilot need?
The 3.5-liter V6 Pilot uses six fuel injectors, one for each cylinder. The products in this comparison are all sold as six-piece sets, but the correct set still depends on the Pilot’s year, engine, connector, and reference number.
Can I use 2016-2020 Pilot injectors in an older Pilot?
Do not assume they are interchangeable. The newer Pilot products listed here use references such as 16010-RLV-305 and 16010-RLV-315, while the older application uses numbers such as 16450-RCA-A01 and 16450-RGL-A01.
Should I replace all six Honda Pilot injectors at once?
A complete set can provide more consistent service when several injectors are worn or the vehicle has high mileage. If testing clearly identifies one failed injector and the others are healthy and properly matched, a single replacement may be sufficient.
Do more injector holes improve fuel economy?
Hole count alone does not guarantee better economy. Spray pattern, flow rate, electrical behavior, engine calibration, and correct fitment all matter, and advertised fuel-economy improvements should be treated as claims rather than assured results.
Are included O-rings ready to install?
They may be ready for installation when undamaged, but inspect every ring for cuts, flattening, dirt, or twisting. A lightly lubricated, correctly seated seal is important for preventing leaks and ensuring the injector fits squarely.
What should I do if the Pilot still misfires after injector replacement?
Stop and check for loose connectors, pinched seals, fuel leaks, and incorrect injector placement. If those items are correct, investigate ignition, vacuum, fuel-pressure, sensor, and compression causes instead of assuming the new injectors are defective.
Final Thoughts
For a 2016-2020 Pilot 3.5L, the SCITOO 6 Holes 6Pcs Fuel Injectors for Honda Pilot 3.5L 2016-2020 are the best overall match in this comparison. For an older compatible Honda application, the Gledewen 6-Piece Fuel Injector Set for 2003-2017 Honda Applications is the better alternative when its reference number matches. In either case, confirm fitment and inspect for leaks before putting the vehicle back into regular service.
For the final decision, my first two recommendations are SCITOO 6 Holes 6pcs Fuel Injectors and Gledewen Gledewen Fuel Injectors 6 PCS. They are the two options I would compare first based on the ranking and buying factors covered above.
