Toyota 4Runner fuel injector questions
How do I know which fuel injectors fit my Toyota 4Runner?
Start with your 4Runner year and engine size. Then compare that information with the fitment chart and injector numbers above.
Are all Toyota 4Runner fuel injectors the same?
No. The 4Runner has used several different four-cylinder, V6, and V8 engines. Injector fitment changes with the year, engine code, and fuel-system design.
Which injectors fit a 1989-1995 Toyota 4Runner?
A 2.4L 22R-E model uses the Bosch four-hole upgrade set that replaces 23250-65040. A 3.0L 3VZ-E model uses a different six-injector Bosch upgrade set that replaces 23250-65020.
Which injectors fit a 2005-2009 4Runner with the 4.7L V8?
The compatible 4.7L 2UZ-FE VVT-i application uses the 23209-0F020, 23250-50060, and Denso 297500-0130 injector family shown on this page.
Do rebuilt 4Runner fuel injectors need programming?
The stock-replacement injectors and application-specific Bosch upgrade sets shown here do not require performance tuning when the correct set is installed in its listed application.
