Finding the right 5.7 hemi fuel injectors can be harder than it looks because several replacement sets share similar OE numbers while covering different model years and vehicles. A good choice needs more than a matching engine size; connector style, vehicle application, included seals, warranty support, and the specific injector family all matter.
My first choice is the Pjvmvo 2005-2018 Hemi-Motor 5.7 Fuel Injectors. This set of eight covers many Dodge, Ram, and Jeep applications, and the listed OE references make it easier to compare with the injectors already in your vehicle. Pjvmvo also states that the parts are inspected, cleaned, and tested before sale, which is useful for buyers replacing a complete bank of injectors.
My alternative choice is A Plus Auto A Plus Auto Fuel Injectors Hemi. My alternative is the A Plus Auto V8 Hemi 5.7L Fuel Injectors. It stands out for detailed flow, resistance, spray-pattern, leakage, and nozzle information, plus a one-year unlimited-mile warranty.
This comparison explains what each set is designed to replace, where the listed fitment overlaps or differs, and which buyer each option best suits. The buying guidance also covers compatibility checks, installation preparation, fuel-system safety, troubleshooting, and ways to avoid common injector-shopping mistakes.

Pjvmvo 2005-2018 Hemi-Motor 5.7 Fuel Injectors
Pjvmvo earns the top position as a broadly applicable replacement set for drivers who need eight injectors for a 5.7L Hemi application. The listed coverage includes Dodge Charger, Ram pickup, and Durango models from 2008 through 2018, along with Jeep Grand Cherokee applications from 2006 through 2019. Because fuel-system parts can vary even within one model line, the seller’s use of Amazon’s confirmed-fit matching is a helpful starting point, although it should not replace checking the vehicle details yourself.
The OE references 05037479AA, FJ732, and RL037479AA give buyers useful comparison points when identifying a replacement. Pjvmvo says the parts are new and undergo inspection, cleaning, and testing before being added to inventory. That stated preparation may provide extra reassurance to a buyer who wants a complete matching set rather than mixing old and replacement injectors.
This option is especially practical when all eight injectors are being replaced at once. A full set can help maintain consistent fuel delivery across the cylinders, but the listing does not provide the same level of flow, resistance, or spray-angle detail as some competitors. Also, a small amount of fuel residue after testing is described as normal, so safe handling and proper priming are important during installation.
Pros
- Complete set of eight new injectors.
- Broad Dodge, Ram, and Jeep fitment coverage.
- Lists several useful OE replacement numbers.
- Seller states that parts are inspected, cleaned, and tested.
Cons
- Detailed flow and spray specifications are not provided.
- Fitment still needs confirmation by vehicle and engine details.
- Fuel residue may remain from pre-sale testing.
My Opinion
This is the strongest all-around pick when broad compatibility and a complete eight-piece set matter most. I would choose it for a standard replacement job after confirming the exact OE number, connector, and model-year application, while buyers demanding extensive published specifications may prefer A Plus Auto.
A Plus Auto A Plus Auto Fuel Injectors Hemi
A Plus Auto is a strong second choice because its listing provides unusually specific operating information for an aftermarket injector set. It identifies four holes, a dynamic flow of 127.0 ±5% ml/min, a static flow of 301.0 ±5% ml/min, a 15 ±1-degree spray cone, and coil resistance of 12.5 ±1 ohms. Those figures give a technically minded buyer more points to compare against the original equipment specification or a trusted repair reference.
The coverage is extensive, including Chrysler 300, Dodge Challenger, Charger, Durango, and Aspen applications, as well as Jeep Commander and Grand Cherokee models. Ram 1500, 2500, and 3500 5.7L applications are also listed, with a specific note about gas-only fitment for a 2012 Ram 2500. That note matters because fuel type and engine configuration can change whether an otherwise similar part is correct.
Pre-installed O-rings can make preparation simpler, while the inlet basket filter is intended to improve filtration. The seller also states that the injectors are checked for leakage, blockage, atomization, injection angle, and nozzle uniformity at different speeds. A one-year unlimited-mile warranty adds useful protection, though the warranty period is shorter than the coverage listed by some other products in this comparison.
Pros
- Detailed flow, resistance, spray, and leakage specifications.
- Broad Chrysler, Dodge, Jeep, and Ram fitment list.
- Pre-installed O-rings and inlet basket filters.
- One-year unlimited-mile warranty.
Cons
- Fitment includes important model-specific exceptions.
- Warranty is shorter than the two-year options listed elsewhere.
- Published specifications should still be compared with the original injector.
My Opinion
A Plus Auto is the best alternative for buyers who want measurable specifications instead of a basic fitment-only listing. Its detailed data and warranty make it appealing for careful DIY planning, but the long application list means extra attention is needed before ordering, especially for Ram trucks and unusual model-year combinations.
Femibon Femibon Fuel Injectors 05037479AA
Femibon offers another complete eight-injector solution centered on the 05037479AA family. Its reference list also includes 5037479AB, 5037479AC, FJ732, and related RL numbers, which may help owners compare superseded or alternate part references. The advertised coverage reaches Dodge Challenger, Charger, and Durango models, Ram 1500, 2500, and 3500 trucks, older Ram pickups, and selected Jeep Commander applications.
The main practical benefit of replacing the full set is consistency. Fuel injectors atomize gasoline into a mist so it can mix with incoming air, and a matched set is generally more straightforward than combining injectors from different sources or wear levels. However, the supplied information does not give a numerical flow rate, spray angle, coil resistance, or O-ring detail, so buyers who need exact specification matching have less data to work with.
Femibon states that the injectors use quality materials and undergo rigorous testing for stable performance. The product also carries a 24-month warranty, which is one of the longer stated coverage periods among these options. That warranty may be valuable for a daily-driven vehicle, but it is still important to understand the seller’s claim process and retain purchase documentation.
The model-year descriptions overlap with several other sets but are not identical in every vehicle line. Verify the exact engine, fuel type, connector, and OE number before installation rather than relying only on a broad “5.7L” match.
Pros
- Complete set of eight injectors.
- Several compatible OE and superseded references are listed.
- Broad Dodge, Ram, and Jeep application coverage.
- 24-month product warranty.
Cons
- Flow, spray, and resistance specifications are not supplied.
- Fitment details should be checked carefully across model years.
- Limited installation information is provided in the listing data.
My Opinion
Femibon is a sensible middle-ground choice for a buyer who values a full set and longer stated warranty coverage. It ranks below the first two because the technical data is less complete, but it remains worth considering when its OE references match the vehicle and the warranty period is a priority.
VELDUROVEL 5037479AC Set of 8 Hemi 5.7L V8 Fuel Injectors
VELDUROVEL focuses on the 5037479AC family and lists a wide range of related references, including 05037479AA through 05037479AD, FJ732, RL037479AA through RL037479AC, and 68060335AA. Its application list covers many Ram 1500, 2500, and 3500 trucks, Dodge Charger, Challenger, and Durango models, Jeep Grand Cherokee and Commander vehicles, Chrysler 300, and Chrysler Aspen.
The listing emphasizes individual inspection and flow testing, which is relevant when replacing all eight injectors and trying to maintain consistent fuel delivery. The stated goal is to restore smooth operation and throttle response where worn injectors may contribute to rough idle, hesitation, misfires, or lower fuel economy. Those symptoms can also result from ignition, vacuum, sensor, or fuel-pressure problems, so replacing injectors should follow a reasonable diagnosis rather than guesswork.
New upper and lower O-rings are included and pre-installed, potentially reducing the need to transfer old seals. That convenience also creates a setup responsibility: inspect every seal before installation and confirm that the vehicle-specific procedure does not require a different arrangement. VELDUROVEL provides a two-year unlimited-mile warranty and customer support, which is useful for high-mileage vehicles or owners who expect substantial driving.
Pros
- Eight-piece set with extensive OE cross-reference coverage.
- Seller states that each injector is inspected and flow tested.
- New upper and lower O-rings are pre-installed.
- Two-year unlimited-mile warranty.
Cons
- Only a small number of customer ratings are supplied.
- Broad fitment increases the need for careful vehicle matching.
- Specific flow and resistance figures are not listed.
My Opinion
VELDUROVEL looks attractive for buyers who want pre-installed seals, a complete set, and extended warranty support. It would move higher for me if more customer-feedback evidence and numerical specifications were available, but its cross-reference list and stated flow testing make it a credible option for the right application.
PremiumpartsWhosale PremiumpartsWhosale a-Premium Fuel Injectors
The A-Premium set is different from the other selections because its listed applications concentrate on earlier vehicles: Chrysler Aspen 2007-2008, Dodge Durango 2004-2009, and Ram 1500, 2500, and 3500 models from 2004 through 2008 with the 5.7L V8. That narrower range explains its lower position in a roundup focused on broad modern 5.7L Hemi coverage, but it may be exactly the right direction for an older truck or SUV.
Its reference numbers include FJ482, 53032713AA, FI11367S, 53032713AB, and RL032713AB. The listing identifies gasoline as the fuel type, a male terminal gender, two terminals, and blade-style terminals. Those details are useful because an injector can look similar while using a different electrical connection or belonging to another OE family.
A-Premium describes the nozzle as designed for fuel atomization, with the intended result of supporting performance and fuel economy. The supplied information does not state that this is a set of eight, nor does it provide flow rate, spray angle, or coil resistance. Confirm the package quantity before ordering if the repair plan involves replacing every injector, and do not assume the earlier FJ482 family fits a later 5.7L Hemi vehicle.
The one-year unlimited-mile guarantee provides a basic layer of purchase protection. With 107 customer ratings supplied, this product also has more feedback evidence than the other listed options, although feedback volume alone cannot replace application verification.
Pros
- Specific fitment for several older Dodge, Ram, and Chrysler vehicles.
- Useful FJ482 and 53032713-series reference numbers.
- Electrical terminal details are provided.
- One-year unlimited-mile guarantee.
Cons
- Narrower and earlier vehicle coverage than the other selections.
- Package quantity is not stated in the supplied data.
- Flow, spray, and resistance specifications are not provided.
My Opinion
This is a targeted option rather than a universal 5.7L replacement. I would consider it for a 2004-2008 Dodge or Ram application after confirming the FJ482 reference and package quantity, but newer Charger, Challenger, Durango, Jeep, or Ram owners should compare a later injector family instead.
How I Selected These Fuel Injectors for 5.7L Hemi Applications
The ranking combines fitment breadth, clarity of OE cross-references, available technical specifications, stated inspection or testing procedures, warranty terms, and the amount of customer-feedback evidence supplied. A product with a high rating but very limited fitment information is not automatically better than a slightly lower-rated option with clearer specifications and a more useful warranty.
For this 5.7 hemi fuel injectors comparison, complete eight-piece sets received practical consideration because many owners replace an entire bank or all cylinders together. That does not mean every vehicle requires eight new parts; a confirmed single-cylinder fault may call for a different repair strategy, especially when budget or diagnosis points to one injector.
Selection takeaway: A broad fitment list is useful, but a matching OE number and connector are more important than the number of vehicles shown on a product page.
I also separated the older FJ482-style application from the later 05037479AA, FJ732, and 5037479AC families. Similar engine displacement does not guarantee interchangeability, so the rankings favor products whose application details give the buyer a clearer path to verification.
How to Choose Fuel Injectors for a 5.7L Hemi
Start with the vehicle identification number, exact model year, engine, fuel type, and original injector number. Then compare the electrical connector, terminal arrangement, seal dimensions, package quantity, and any available flow or resistance data rather than shopping by “5.7L” alone.
- Match the OE number: Use the number printed on the original injector or the number confirmed by a trusted parts catalog. Numbers such as FJ732 and FJ482 point to different application families.
- Confirm the vehicle: Check model, year, drivetrain where relevant, and whether the listing specifically says gas or gasoline.
- Check quantity: Determine whether the package contains one injector or a complete set of eight before planning the repair.
- Compare technical data: Flow rate, coil resistance, spray angle, hole count, and leakage information can help identify a closer match.
- Consider warranty support: Keep the invoice and understand the return or replacement process before opening the fuel-system package.
Why OE numbers matter more than engine size
Chrysler, Dodge, Jeep, and Ram vehicles can use different injector families across years and platforms even when they share the 5.7L Hemi name. A later Ram truck, an older Durango, and a Chrysler 300 may require different seals, connectors, calibration, or reference numbers.
Use marketplace fitment tools as a screening aid, not as the only authority. If the original part number conflicts with the listing, pause and verify through the vehicle manufacturer’s parts information or a reputable parts specialist.
Choosing a full set versus individual replacement
A complete set makes sense when several injectors are failing, the mileage is high, or the goal is consistent replacement across all cylinders. It can also avoid mixing old injectors with new parts that may have different wear patterns.
Replacing all eight is not automatically the best answer for every fault. A clogged filter, fuel-pressure problem, wiring issue, vacuum leak, bad ignition coil, or sensor problem can imitate injector trouble, so diagnosis should guide the quantity purchased.
Installation Preparation and First Use
Fuel-system work should begin with a cool engine, good ventilation, and no smoking, open flames, or spark-producing tools nearby. Relieve fuel pressure according to the vehicle’s service procedure, disconnect the battery when appropriate, and have absorbent material ready for small spills.
- Compare the new injector with the removed part before opening the fuel rail.
- Inspect connectors, clips, filters, and every O-ring for damage or distortion.
- Use the correct lubricant approved for the injector seals; do not force a dry O-ring into the rail.
- Keep dirt away from the rail and intake openings during removal and installation.
- Pressurize the system and inspect for leaks before starting the engine.
- Start the vehicle, let it idle, and check again for fuel seepage or an abnormal smell.
Pre-installed O-rings can save time, but they are not a reason to skip inspection. A seal that is cut, rolled, pinched, or seated unevenly can leak even when the injector itself is correct.
Safety reminder: Never treat a fuel smell, wet rail, or dripping injector as a minor issue. Shut the vehicle down and correct the leak before driving.
How to Troubleshoot Injector Problems After Installation
A rough idle immediately after installation can result from an unplugged connector, a pinched seal, a vacuum hose left disconnected, or air and fuel-system issues created during the repair. Scan for diagnostic trouble codes, inspect every connector, and compare the symptoms with the original problem before assuming the new injectors are defective.
Useful checks for beginners
- Look for fuel leaks around the upper and lower seals.
- Confirm every injector connector is fully locked.
- Check for damaged wiring near the fuel rail.
- Listen for an unusual change in idle or a persistent misfire.
- Verify fuel pressure and ignition components if the fault remains.
Do not continue driving with a severe misfire, strong fuel odor, or flashing check-engine light. Unburned fuel can create additional engine or emissions-system problems, and a leak presents an immediate fire risk.
Common Mistakes to Avoid
Most injector-buying problems come from assuming that all 5.7L Hemi parts are interchangeable. Installation mistakes can be just as costly as ordering the wrong part, particularly when old seals or contaminated fuel-system components are reused.
- Ordering from engine size alone without checking the OE number.
- Ignoring an application note such as gas-only fitment.
- Mixing injector families because they look physically similar.
- Reusing flattened, brittle, cut, or fuel-damaged O-rings.
- Skipping a leak check after the fuel rail is reinstalled.
- Replacing injectors without checking for ignition or fuel-pressure faults.
- Discarding packaging and purchase records before confirming proper operation.
Best practice: Photograph the original injector, connector, and OE number before removal. Those photos can resolve fitment questions before the replacement is installed.
FAQ About Hemi Fuel Injector Replacement
How many injectors does a 5.7L Hemi use?
A typical 5.7L Hemi V8 uses eight fuel injectors, one for each cylinder. However, the correct replacement package may contain one injector or eight, so confirm the quantity before ordering.
Are FJ732 and FJ482 injectors interchangeable?
Do not assume they are interchangeable. The supplied product data places FJ732 with later 05037479AA-related applications and FJ482 with earlier Dodge, Ram, and Chrysler applications, so the OE number and vehicle fitment must match.
Should all eight fuel injectors be replaced together?
Replacing all eight can provide a consistent set when several injectors are worn or the vehicle has high mileage. If testing confirms one defective injector and the others are healthy, a single replacement may be appropriate, provided the replacement matches correctly.
Can bad injectors cause rough idle or hesitation?
They can contribute to rough idle, hesitation, misfires, and reduced fuel economy when fuel delivery is uneven. Those symptoms also come from ignition, vacuum, wiring, sensor, or fuel-pressure faults, so diagnosis is important before purchasing a complete set.
Do new fuel injectors need programming?
Many replacement injectors do not require individual programming, but the vehicle may need diagnostic-code clearing or an idle and fuel-trim relearn procedure. Follow the service information for the specific year and model.
How long should replacement fuel injectors last?
Service life depends on fuel quality, contamination, vehicle use, installation quality, and the injector design. Keeping the fuel system clean and addressing filters, leaks, and drivability symptoms promptly can help protect the replacement parts.
Final Thoughts
The Pjvmvo 2005-2018 Hemi-Motor 5.7 Fuel Injectors are my first recommendation for broad application coverage and a complete eight-piece replacement set. Choose the A Plus Auto V8 Hemi 5.7L Fuel Injectors instead if detailed specifications, pre-installed O-rings, and a clear one-year warranty are more important to your decision. In either case, verify the OE number and vehicle fitment before ordering 5.7 hemi fuel injectors.
For the final decision, my first two recommendations are Pjvmvo 2005-2018 Hemi-Motor 5.7 Fuel Injectors and A Plus Auto A Plus Auto Fuel Injectors Hemi. They are the two options I would compare first based on the ranking and buying factors covered above.
