Every injector is covered against failure caused by defects in original manufacture by our lifetime warranty

This injector set contains high impedance injectors matched to the saturated injector signal generated by this vehicle’s OEM ECU, OR is suitable for use with an aftermarket ECU made or set up for high impedance injectors.

This set of injectors requires you to change the injector plug on the wiring harness in your car. This can be done by soldering in the pigtails (included with purchase) to replace the plugs currently on your harness, or you can choose to purchase the optional plug-n-play adaptors which will convert from the type of plugs on these injectors to the plugs on your harness without any need for cutting or soldering.

This plug conversion is made necessary because FIC always chooses to provide brand new, unused injectors for its performance applications. We do not believe that increasing the chance of a failure due to using remanufactured or core program based injectors is ever warranted
