Choosing a replacement nissan altima fuel injector can be confusing because the correct part depends heavily on the Altima’s year, engine size, and original equipment number. A set that fits a 2010 2.5L engine may not be suitable for a 2019 model, even when the parts look similar.
My first choice is Pjvmvo. Its clear 2007–2013 2.5L fitment range, OE number references, and set of four make it a practical choice for owners replacing the complete injector group. The supplied information also says the parts are inspected, cleaned, and tested before sale.
My second choice is XLNTAPS XLNTAPS Set of 4 Upgraded 18 Holes Fuel Injectors. My alternative is XLNTAPS Set of 4 Upgraded 18 Holes Fuel Injectors for Nissan Altima, NV200, and Rogue. It suits drivers with newer 2.0L or 2.5L applications from the listed years who want a complete set with high-temperature Viton O-rings and several cross-reference numbers.
This comparison covers five replacement sets, their compatibility details, construction claims, customer-feedback evidence, and practical limitations. The buying guidance then explains how to verify fitment, prepare for installation, avoid common mistakes, and decide whether replacing one injector or all four makes sense.
5 Best Nissan Altima Fuel Injector
I selected these products by comparing stated vehicle coverage, engine applications, OE numbers, useful design details, available customer-feedback evidence, and the completeness of each four-piece set. The ranking also considers brand variety where a different product offered a meaningful alternative for a different Altima generation, without claiming hands-on testing.

Pjvmvo
Pjvmvo earns the top position because its application range is especially clear for owners of a 2007–2013 Nissan Altima with the 2.5L engine. The set contains four new injectors, which is useful when several cylinders show similar age-related symptoms or when a complete, matched replacement is preferred over mixing old and new parts.
The listed OE references include FJ1020, 16600-JA00B, and 16600-JA000. Those numbers give shoppers a practical way to compare the replacement against the injector already installed, although the year, engine, and Amazon fitment result should still agree before ordering. Pjvmvo also states that the parts are inspected, dismantled, cleaned, and tested before being added to inventory.
That preparation claim adds confidence for a budget replacement, but it should not be interpreted as a substitute for checking the rest of the fuel system. A clogged filter, wiring problem, vacuum leak, or poor electrical connection can create symptoms that look like injector failure. The product’s 4.5-star score from 47 customer ratings is also the strongest feedback signal among the selections.
Pros
- Clear fitment for 2007–2013 Altima 2.5L models.
- Complete set of four new injectors.
- Multiple OE references support part-number comparison.
- Supplier states that the parts are cleaned and tested.
Cons
- Not listed for newer Altima generations.
- Professional installation may still be needed.
- Fitment should be confirmed before ordering.
My Opinion
This is the most balanced choice for an older 2.5L Altima because it combines the clearest target application with the largest customer-feedback sample in this group. It is less suitable if the vehicle is outside the 2007–2013 range or uses a different engine.
XLNTAPS XLNTAPS Set of 4 Upgraded 18 Holes Fuel Injectors
XLNTAPS is a strong second choice for drivers whose vehicles fall within the listed 2015–2018 Altima 2.5L range. The set is also identified for the NV200 and selected Rogue applications, so it may appeal to households maintaining more than one Nissan vehicle with related fuel-system needs.
The 18-hole design is presented as a way to support fuel atomization, while the composite body is described as corrosion resistant. The stated high-temperature Viton O-rings are intended to preserve sealing under demanding heat conditions, which matters because a poor seal can allow fuel vapor or liquid leakage around the injector seat.
Several cross-reference numbers are supplied, including FJ1280, FJ1446, 166009HP0A, 166009HU0A, and FBY2855. That broad reference list is helpful, but it also makes careful verification more important rather than less; matching one number alone does not guarantee that the vehicle’s year and engine are correct. With a 4.2-star score from four ratings, the available customer evidence is positive but limited.
Pros
- Useful coverage for listed 2015–2018 Altima 2.5L models.
- Four-piece set supports complete replacement.
- High-temperature Viton O-rings are a useful sealing detail.
- Multiple OE and aftermarket references are provided.
Cons
- Customer-feedback sample is small.
- Not listed for every Altima year.
- “Upgraded” does not remove the need for exact fitment checking.
My Opinion
This is the best alternative for a later Altima owner who values the stated sealing materials and 18-hole design. I would place it behind Pjvmvo mainly because its feedback sample is smaller and its application list requires closer year-by-year checking.
VekAuto 166006CA0A Fuel Injectors
VekAuto targets a much newer group of vehicles than the first two selections. It is listed for Nissan Altima S, SL, SR, and SV trims with the 2.5L engine from 2019–2024, plus a 2021 Rogue 2.5L application. That narrow, newer-vehicle focus makes it a useful option when an older injector set would clearly be wrong.
The main identification numbers are 166006CA0A, 16600-6CA0C, and 16600-6CA0B. The product description also calls out high-impedance coils and efficient fuel spray, connecting the injector design to fast cold starts, fuel consumption, and general engine response. These are stated product characteristics, not independently verified performance results.
VekAuto includes four pieces and durable rubber O-rings intended to contain fuel vapors and maintain a seal. The supplied guidance recommends professional installation and notes that new injectors may require a new or updated tune. That is an important limitation for buyers expecting a simple plug-in repair, particularly if the vehicle has other engine modifications or an existing calibration issue.
Pros
- Focused fitment for 2019–2024 Altima 2.5L trims.
- Four injectors are included as a set.
- Multiple 16600-series OE numbers are listed.
- Sealing and high-impedance coil details are explained.
Cons
- Very limited customer-feedback evidence.
- Professional installation is recommended.
- A tune may be required or advisable after installation.
My Opinion
VekAuto is the most relevant selection for a 2019–2024 2.5L Altima, but it is not a universal Nissan replacement. Its newer fitment and installation guidance are valuable, while the small two-rating evidence base means buyers should rely heavily on OE-number and vehicle verification.
FIREMOTOO 18-Hole Fuel Injector Pack
FIREMOTOO offers another four-piece 18-hole set for the 2014–2018 Nissan Altima L4 2.5L. It also lists selected NV200 and Rogue applications, making it a direct competitor to the XLNTAPS set for shoppers comparing several aftermarket options within the same general generation.
The product information connects its spray pattern, spray angle, and fuel volume per millisecond with OE specifications. In practical terms, the intended benefit is consistent fuel delivery across the cylinders rather than simply adding more fuel. The stated metal-and-plastic construction and O-rings are designed to support installation and sealing in demanding conditions.
FIREMOTOO provides an extensive cross-reference list, including FBY2855, FJ1280, FJ1446, FIJ0052, 84212412, 166009HP0A, and 166009HU0A. That makes part-number comparison convenient, but shoppers should use the vehicle’s year, engine, and existing injector number together. The five-star score comes from only two ratings, so it is encouraging but not a broad measure of ownership experience.
Pros
- Targets the 2014–2018 Altima 2.5L range.
- Four injectors and 18-hole spray design are specified.
- Large list of cross-reference numbers.
- Product description explains the intended fuel-economy benefit.
Cons
- Only two customer ratings are available.
- Fitment overlaps other products, so comparison is necessary.
- Construction details do not replace OE-number verification.
My Opinion
FIREMOTOO deserves consideration when its listed cross-reference matches the old injector and the vehicle is a 2014–2018 2.5L Altima. It is a sensible alternative to XLNTAPS, but the smaller feedback sample prevents a stronger ranking.
NOVIX ZYLTOR NOVIX ZYLTOR FBY2855 4PCS Fuel Injector Replacement Altima
NOVIX ZYLTOR is aimed at Nissan Altima, NV200, and Rogue applications from 2015–2021, covering both 2.0L and 2.5L references in the supplied information. Its FBY2855 designation and OE references 84212412, FJ1280, and FJ1446 make it particularly relevant to shoppers already identifying one of those numbers on the original part.
The set is described as corrosion resistant and fitted with fluorosilicon O-rings. Those details are intended to support consistent fuel delivery and sealing over time. The product is also positioned as a replacement for injectors associated with rough idle, poor acceleration, and lost engine power, although those symptoms can also come from ignition, air, sensor, or fuel-pressure problems.
A one-year warranty and customer support are listed, which gives this option a useful ownership advantage when the fitment is correct. However, no customer-feedback volume is supplied, so there is less customer-feedback evidence to weigh than with Pjvmvo, XLNTAPS, or the other ranked products. The broad 2015–2021 application range should be treated as a starting point, not automatic confirmation for every trim.
Pros
- Four-piece set for listed 2015–2021 Nissan applications.
- Useful FBY2855 and OE-number references.
- Fluorosilicon O-rings are specified.
- One-year warranty and customer support are listed.
Cons
- No customer-feedback count is supplied.
- Broad application range requires careful vehicle matching.
- Symptoms listed are not unique to failed injectors.
My Opinion
NOVIX ZYLTOR is worth considering when warranty coverage and the listed FBY2855 references matter most. It ranks fifth because the available product information gives less customer evidence and less detailed vehicle-by-vehicle separation than the higher options.
How I Selected These Nissan Altima Fuel Injector Options
The selection process focused on fitment first, because a beautifully made injector is still the wrong purchase if its electrical connection, flow characteristics, or sealing dimensions do not match the engine. I then compared OE references, set size, stated construction, installation notes, warranty information, and the amount of customer-feedback evidence available for each listing.
The exact phrase nissan altima fuel injector covers several very different vehicle generations in this comparison. Pjvmvo is centered on 2007–2013 2.5L models, the middle choices focus mainly on 2014–2018 or 2015–2021 applications, and VekAuto is directed toward 2019–2024 2.5L Altimas. That spread is why the ranking is not based on a single feature such as hole count.
Fitment is the first filter; performance claims matter only after the year, engine, connector, and OE number agree.
Customer scores were treated as supporting evidence rather than proof. Pjvmvo has the largest stated sample, while several other products show only two or four ratings, and NOVIX ZYLTOR does not provide a customer-feedback volume in the supplied information. A small sample can still be useful, but it should not outweigh a clear compatibility mismatch.
How to Choose the Right Nissan Fuel Injector Set
Start with the vehicle identification label, engine size, model year, and the number printed on the existing injector or its packaging. Then compare that information with the product’s application range and cross-reference numbers before considering design details such as hole count or O-ring material.
- Confirm the exact Altima year and engine, not just the Nissan badge.
- Match at least one OE or replacement number, preferably alongside vehicle fitment.
- Check whether the package contains four injectors when replacing the full set.
- Look for installation or tuning guidance if the product says calibration may be needed.
- Consider warranty and customer-support terms when evidence is limited.
Year and engine compatibility
Altima generations can use different injector designs even when they share a 2.5L displacement. The listed products demonstrate that clearly: a 2007–2013 application is not interchangeable by default with a 2019–2024 application. Trim names such as S, SL, SR, or SV can help narrow the search, but the engine and OE number remain more important.
OE numbers and cross-references
Numbers such as FJ1020, FBY2855, FJ1280, 166009HP0A, and 166006CA0A are useful comparison points. They are not permission to assume every similar-looking number is interchangeable. Check punctuation variations, such as 16600-9HP0A versus 166009HP0A, and compare the result with the vehicle selector and the part removed from the car.
One injector or a complete set?
A single failed injector may be the only defective part, but a four-piece set can be reasonable when all injectors are original and have similar mileage. Replacing the complete group may make cylinder-to-cylinder behavior more consistent, though it also increases the initial parts cost and gives you four components to verify before installation.
If diagnosis points to one cylinder, test the injector circuit and compare cylinder behavior before automatically replacing everything. A complete set is more defensible when multiple injectors are dirty, the engine has high mileage, or the available product is sold only as a four-pack.
Before Installing a Replacement Injector
Fuel-system work deserves preparation because gasoline is flammable and contamination can damage a replacement part. Gather the correct seals, basic hand tools, a clean work area, and a way to relieve fuel pressure according to the vehicle’s service procedure.
- Park outside or in a well-ventilated area away from flames and sparks.
- Disconnect the battery when the service procedure calls for it.
- Relieve fuel pressure before loosening the rail or injector connections.
- Keep dirt away from the open fuel rail and intake ports.
- Compare every new injector with the old part before removing all components.
Do not reuse damaged, flattened, cut, or dried-out O-rings. A replacement injector that fits electrically can still leak if the seal is pinched or installed without appropriate preparation. The supplied product information mentions O-ring materials, but it does not provide a complete vehicle-specific installation procedure.
Safe Installation and First Start
Installation is best handled by someone comfortable with fuel-system repairs, and VekAuto specifically recommends professional installation. The injector should seat straight, the electrical connector should lock fully, and the fuel rail should be tightened evenly rather than forced into position.
After installation, inspect for leaks before normal driving. Turn the ignition on and off as appropriate for the vehicle to build pressure, then check the rail, injector bases, and nearby connections. If fuel appears, smells strongly, or drips, shut the vehicle down and correct the problem before starting again.
The first start may require a little extra cranking while pressure stabilizes, but repeated extended cranking is not a substitute for diagnosis. Watch for an uneven idle, warning light, fuel odor, or immediate misfire. These signs require stopping and checking the connector, seal, injector seating, and wiring.
Do New Injectors Need a Tune?
Not every stock replacement requires custom tuning, but the supplied VekAuto information warns that new injectors can require a new or updated tune. That caution matters most when the replacement differs in flow characteristics, the engine has modifications, or the vehicle already uses nonstandard calibration.
For a direct replacement matching the original OE number, the vehicle’s existing control system may be designed to operate normally, but that should not be assumed without checking the application. If fuel trims move sharply, the engine runs rich or lean, or a warning light appears, have the system scanned rather than continuing to drive normally.
How to Diagnose an Injector Problem
Rough idle, hesitation, poor acceleration, hard starting, and reduced engine power can be connected to injector trouble, but none of those symptoms proves the injector is bad. Ignition coils, spark plugs, vacuum leaks, fuel pressure, sensors, and wiring can produce similar behavior.
A sensible diagnostic path includes scanning for trouble codes, checking the affected cylinder, inspecting the connector, and comparing injector electrical behavior when appropriate. A professional can also perform tests that evaluate fuel delivery or cylinder balance. Avoid replacing parts solely because one symptom resembles a listing description.
A misfire code identifies a cylinder or operating condition; it does not automatically identify the injector as the failed component.
Maintenance and Long-Term Ownership Tips
Replacement injectors generally benefit from clean fuel, a healthy fuel system, and prompt attention to leaks or drivability changes. Use fuel from reputable sources and follow the maintenance schedule for the vehicle rather than relying on aggressive cleaning products as a cure-all.
- Fix fuel leaks or strong fuel odors immediately.
- Do not ignore a persistent check-engine light or repeated misfire.
- Keep the air-intake and electrical connections clean and secure.
- Replace related seals when they are damaged or no longer resilient.
- Record the injector part number and installation date for future service.
Fuel-system cleaners may help with some deposits, but they cannot correct a failed coil, damaged connector, leaking seal, or incorrect injector. If the engine problem began immediately after installation, recheck fitment and seating before assuming the new parts are defective.
Common Mistakes to Avoid
Most avoidable problems come from ordering by appearance, skipping the OE-number comparison, or treating every Altima 2.5L engine as identical. Careful preparation is less expensive than dealing with a leak, a persistent misfire, or an incorrect set that must be removed.
- Ordering solely by model name without confirming the year and engine.
- Assuming an 18-hole injector fits every Nissan 2.5L application.
- Mixing injectors with different references or unknown flow characteristics.
- Reusing damaged O-rings or installing them dry and twisted.
- Starting the engine without checking for fuel leaks.
- Blaming injectors before checking ignition, wiring, and fuel pressure.
- Ignoring a manufacturer note about professional installation or tuning.
When Replacement Is Better Than Cleaning
Cleaning may be worth discussing when an injector is dirty but electrically sound and mechanically intact. Replacement becomes more practical when the injector leaks, has a damaged body or connector, fails an electrical test, or continues to cause a cylinder-specific problem after proper cleaning.
A matched four-piece set can also make sense when several injectors are worn or when the product is sold as a complete package. The decision should be based on diagnosis and cost, not simply on the belief that every injector needs to be replaced whenever one cylinder misfires.
FAQS About Nissan Altima Fuel Injector
Which replacement injector fits a 2007–2013 Nissan Altima 2.5L?
The Pjvmvo four-piece set is specifically listed for Nissan Altima 2.5L models from 2007–2013. Confirm the vehicle details and compare OE numbers FJ1020, 16600-JA00B, or 16600-JA000 before purchase.
Which injector set fits a 2019–2024 Nissan Altima?
The VekAuto set is listed for Nissan Altima S, SL, SR, and SV trims with the 2.5L engine from 2019–2024. Its supplied OE references include 166006CA0A, 16600-6CA0C, and 16600-6CA0B.
Should all four Altima injectors be replaced together?
Not always. If testing identifies one failed injector and the others are healthy, replacing one may be sufficient. A four-piece set can be sensible when the injectors have similar age, several cylinders show problems, or consistent replacement is preferred.
Can a rough idle mean a Nissan Altima injector is bad?
Yes, but rough idle can also result from ignition problems, vacuum leaks, wiring faults, fuel-pressure issues, or sensors. Diagnose the affected cylinder and related systems before buying replacement parts.
Do replacement Altima injectors need programming?
A direct replacement may work with the existing control system, but the supplied VekAuto information warns that new injectors may require a new or updated tune. Follow the product guidance and check fuel trims or fault codes after installation.
Are 18-hole injectors interchangeable between Altima years?
No. Hole count alone does not establish compatibility. Connector design, flow characteristics, physical dimensions, OE number, and vehicle application must all match.
Final Thoughts
For an older 2.5L model, Pjvmvo Pjvmvo is the most convincing overall choice because of its focused fitment, four-piece format, OE references, and stronger customer-feedback sample. For a later application, choose XLNTAPS Set of 4 Upgraded 18 Holes Fuel Injectors for Nissan Altima, NV200, and Rogue when its year, engine, and part number match. Whichever set you choose, verify compatibility before installing a nissan altima fuel injector and inspect carefully for leaks afterward.
For the final decision, my first two recommendations are Pjvmvo and XLNTAPS XLNTAPS Set of 4 Upgraded 18 Holes Fuel Injectors. They are the two options I would compare first based on the ranking and buying factors covered above.
