Wiring and Installation
The IS168-0525H injector set requires an injector plug conversion when installed with the factory wiring harness. Fuel Injector Clinic includes PGTUSC6 pigtails that can be soldered into the vehicle harness to replace the existing injector plugs. For an installation without cutting or soldering the factory harness, optional PADPUtoJ6 plug-and-play adapters can be added to connect the injectors to the existing wiring.
Fuel Injector Clinic chooses brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. The IS168-0525H set is supplied with the O-rings required for the listed factory application. If your vehicle uses an aftermarket fuel rail or another non-standard fuel system configuration, injector compatibility should be verified before ordering.
