525cc (58 lbs/hr at OE 58 PSI fuel pressure) FIC Fuel Injector Clinic Injector Set for LS1 engines (High-Z) (is301-0525h)

Fuel Injector Clinic's high performance fuel injector sets are precisely flow matched to within 1%. Each injector within each set is individually numbered and results for each injector are listed on a detailed flow sheet included with the set.

Fuel Injector Clinic's high performance fuel injectors are flow tested and rated at 43.5psi (3Bar) at 90 degrees F fuel temperature using CF-16B calibration fluid.

Superior short pulse width control and tight manufacturing tolerances make these injectors easy to tune and provide great drivability.

Fuel Injector Clinic injectors are set up to and include all o-rings needed to fit the factory application for the listed vehicle. For aftermarket or other unusual setups please contact us prior to placing your order to make sure you receive injectors that fit properly.

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

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.
