If you have questions about fit, please call us with your VIN number to verify this is the correct injector.

We recommend replacing the fuel feed tube when replacing these injectors. The tubes can contain leftover debris from previous failures causing failure of the replacement injector. The mating surface of the tube can also damage easily and cause fuel leaks between the fuel tube and the injector.
