Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set for LS3, LS7, LSA, L76, L92 & L99 Engines (IS303-2150H)
The Fuel Injector Clinic IS303-2150H is engineered for the most demanding GM Gen IV LS performance builds where maximum fuel delivery and exceptional tuning characteristics are equally important. Designed specifically for LS3, LS7, LSA, L76, L92, and L99 engine applications, this complete set of eight saturated high impedance fuel injectors delivers enormous flow capacity while maintaining impressive idle quality and part-throttle drivability. Featuring Fuel Injector Clinic's latest injector technology and proprietary Data Match Technology, the IS303-2150H provides the precise fuel control required for extreme horsepower combinations.
Despite their massive 2150 cc/min flow rating, these injectors offer outstanding short pulse width control thanks to Fuel Injector Clinic's advanced dynamic flow matching process. Each injector is individually serial numbered and supplied with a detailed Data Match Sheet containing comprehensive flow and latency information for accurate ECU calibration. This kit includes PGTDEN8 injector pigtails, while optional PADPDtoU8 Plug and Play adapters are available separately for installers who prefer not to modify the factory wiring harness. Plug and Play GM ECU calibration data is also available directly from Fuel Injector Clinic.

Important Fuel Compatibility
The IS303-2150H is compatible with pump gasoline and E85. Due to the injector's internal seal design, do not use VP Import, Q16, or any other MTBE oxygenated race fuels. Exposure to MTBE oxygenated fuels can cause the internal seal to swell, significantly reducing injector flow and performance.
If the injectors are operated with E85 or other alcohol-based fuels, Fuel Injector Clinic recommends following proper maintenance and storage procedures to minimize the potential for corrosion during extended periods of non-use.

FAQs
Do these injectors require wiring modifications?
Yes. The IS303-2150H includes PGTDEN8 injector pigtails for wiring conversion. Optional PADPDtoU8 Plug and Play adapters are available separately for installers who prefer not to cut or solder the factory harness.
Can these injectors be used with Q16 or VP Import fuel?
No. The IS303-2150H is designed for pump gasoline and E85. It should not be used with Q16, VP Import, or any other MTBE oxygenated race fuels because those fuels can damage the injector's internal seal and reduce fuel flow.
