Fuel Injector Clinic Holley GM composite intake Injector Set (8 Cyl, High-Z)

Fuel Injector Clinic injector set for the Holley GM composite intake: 8 saturated / high impedance injectors, available from 540cc to 2150cc/min. Select your injector size above. Every set is new (never remanufactured), flow matched, and covered by FIC's lifetime warranty.

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 injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually serial numbered and the results are provided on the Data Match Sheet providing the most complete flow matching and latency value information available in the industry today.

2150cc injector: This massive high performance injector is in a class of its own when low end throttle response and short pulse width control is required. State of the art Data Match Technology dynamic flow matching is used during the production of these injector sets due their large flow rate. This significantly improves the ECU’s ability to control these injectors in the sub 2ms pulse width area, typical of idle and part throttle conditions.

CAUTION! The internal construction of this 2150cc/min injector includes a seal that has been found to swell when in contact with MTBE from oxygenated fuels like Q16 or VP Import. This swelling causes a significant reduction in flow through the injector and therefore renders it unsuitable for use with MTBE oxygenated fuels. Please be sure to follow the care instructions for these injectors since there are potential corrosion issues that may arise from prolonged disuse while exposed to alcohol based fuels (E85, etc.)

1440cc injector: Fuel Injector Clinic’s 1440cc/min high impedance injector fits nicely between our 1200 and 1650cc injectors. The 1440cc injector is compatible with all race fuels and has excellent idle performance in street driven cars while still providing enough fuel to support higher horsepower output on both E85 and gasoline.

1440cc injector: The 1440cc high impedance injector can be used with any fuel type based on the stainless alloy valve construction. It is compatible with pump gasoline, E85, Q16, VP Import, FTW and other MTBE oxygenated race fuels!

1650cc injector: Fuel Injector Clinic’s 1650cc/min high impedance injector is the largest high impedance injector compatible with all race fuels and has excellent idle performance in street driven cars while still providing enough fuel to support higher horsepower output on both E85 and gasoline.

The 1650cc high impedance injector can be used with any fuel type based on the stainless alloy valve construction. It is compatible with pump gasoline, E85, Q16, VP Import, FTW and other MTBE oxygenated race fuels!

Sizes listed with pigtails: 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.
