Nissan Altima Injector Fitment Guide
Nissan Altima injectors are not interchangeable simply because two cars share the same engine size. Start with the model year and engine, then verify emissions. For some years, you need production date or the number stamped on the original injector before ordering. We can help, contact us.
Quick Fitment Finder
Choose the engine first. This guide directly links the rebuilt OEM Altima injector sets currently offered for selected 2002–2018 applications. Applications marked “verify first” require an emissions, body-style, production-date or original-part-number check.
Sets of 4 for QR25DE applications
Factory replacement set for the third-generation Altima 2.5L QR25DE.
Does not fit: 3.5L V6 Altima applications.
View the 16600-8J010 SetFederal-emissions replacement set for the applicable Altima 2.5L sedan and coupe.
Does not fit: California-emissions 2.5L, Altima Hybrid or the new-body 2013 Altima sedan.
View the 16600-JA000 SetCalifornia-emissions and Hybrid applications use a different injector family than 16600-JA000. The new-body 2013–2018 Altima 2.5L sedan and 2019-and-newer direct-injection Altima models also use different injectors. Do not substitute one of the sets above based only on the 2.5L engine size.
Send Us Your VIN or Part NumberSets of 6 for verified VQ35DE applications
Early VQ35DE set. The 2003–2004 changeover makes the original injector number especially important.
Does not fit: Vehicles originally equipped with 16600-7Y000 / 7Y00A.
View the 16600-AE060 SetLater third-generation Altima V6 set. Confirm the original number on crossover-year cars.
Does not fit: Early cars originally equipped with 16600-AE060.
View the 16600-7Y000 SetFactory replacement set for fourth- and fifth-generation Altima 3.5L VQ35DE applications.
Does not fit: 2.5L Altima or 2019-and-newer Altima applications.
View the 16600-JK20A SetNissan used more than one injector design around this production change. Do not choose AE060 or 7Y000 from the model year alone. Match the number on the original injector and, when needed, the vehicle production date before ordering.
A 2.5L Altima can use different injectors depending on generation, body style and emissions certification. A 3.5L Altima can also change injector families by production date and model generation. The OEM number is the final confirmation whenever the application overlaps.
Quick Reference
Use this chart to narrow the application, then follow the verification note before purchasing.
We do not have these cores in stock.
Set of 4. Verify the number on the original injector.
Production-date and part-number verification required during the crossover.
Do not substitute for AE060 without matching the original number.
Does not cover California-emissions, Hybrid or new-body 2013 sedan applications.
Set of 6. Earlier 16600-JA10A is superseded by 16600-JK20A.
Uses a different injector family than JA000. Contact us before ordering if your original number is not listed above.
Use different high-pressure/direct-injection components. None of the port-injector sets above can be substituted.
Prevent a Wrong Order
The best fitment check combines vehicle information with the number and physical design of the injector already installed.
Send us the Altima year, engine size, emissions style, and sedan or coupe. If you have part # or a clear picture of the original injector. For a 2003–2004 V6, include the production date from the driver-door label.
Model-Specific Guide
The Altima name spans several engine and fuel-system generations, so a useful fitment page must separate them rather than treating every 2.5L or 3.5L application as the same.
The QR25DE four-cylinder uses the 16600-8J010 / Denso 195500-4390 injector family represented by the linked set of four.
Early VQ35DE cars can use 16600-AE060, while later cars use 16600-7Y000 / 7Y00A. The overlapping catalog years make the original number and production date more reliable than the model year alone.
The 16600-JA000 / JA00B set is for the applicable Federal-emissions QR25DE application. California-emissions and Hybrid vehicles use a different family, and the 2013 sedan/coupe body split must be respected.
The Altima VQ35DE application moves to 16600-JK20A, which supersedes 16600-JA10A. This is not an injector for 2019-and-newer Altimas.
Later Altimas use different direct-injection systems. Fitment should be verified from the exact engine and injector number rather than matched to one of the earlier port-injector sets.
Diagnosis
Injector problems can appear as drivability or fuel-control issues, but these symptoms can also be caused by ignition, wiring, air leaks, fuel pressure, sensors or mechanical faults.
A misfire code does not automatically prove that the injector is bad. Confirm ignition, compression, wiring and fuel pressure as appropriate, or move injector to another cylinder and see if problem follows.
Why Precision Auto Injectors
These sets start with genuine factory original injector cores rather than new replicas, and unverified replacement injectors.
Frequently Asked Questions
No. The 2002–2006 2.5L uses a different injector family from the applicable 2007–2013 Federal-emissions cars, and the California, Hybrid, new-body 2013–2018 sedan and 2019-and-newer direct-injection applications introduce additional differences.
The verified application shown on this page is OEM 16600-8J010 / Denso 195500-4390, sold as a set of four. Match the number on the original injector before ordering.
The later 3.5L application generally uses 16600-7Y000 or its superseding number 16600-7Y00A. Because Nissan used an earlier AE060 family around the preceding production crossover, the original number remains the safest confirmation.
No. The JA000 / JA00B set linked here is the Federal-emissions application. Altima Hybrid and California-emissions 2.5L applications use a different injector family, commonly associated with 16600-JA00A / 16600-9DE0B.
The 2013 model year includes a carryover coupe and a new-body sedan. The 2.5L injector application is not the same across those body styles, and Federal versus California emissions can further change the required part.
They are different injector families used around the early Altima 3.5L production change. They should not be treated as interchangeable simply because both are listed for VQ35DE cars. Match the original number and production date.
The correct factory-style replacement injector set normally does not require performance tuning. The important step is installing the exact application and correcting any underlying wiring, pressure, ignition or mechanical problem that caused the symptoms.
That depends on the diagnosis and condition of the remaining injectors. Replacing a complete professionally tested set can provide more consistent cylinder-to-cylinder delivery, while an isolated electrical or mechanical failure may sometimes be handled individually after testing.
Send us your year, 2.5L or 3.5L engine, sedan or coupe body style, emissions label, VIN and original injector number. We will help compare the available applications before you order.
Fitment information should be confirmed against the original injector number whenever an emissions or production split applies.
