Bridge the gap between Fuel Injector Clinic's popular 1200cc and 1650cc offerings with the Fuel Injector Clinic IS801-1440H Fuel Injector Set. Designed specifically for the 2000-2006 BMW E46 M3 and 2006-2008 BMW Z4 M, this complete set of six 1440cc saturated (high impedance) ball and seat injectors provides the ideal balance of massive fuel delivery, outstanding drivability, and broad fuel compatibility. Whether you're building a high-horsepower street car or a serious competition vehicle, these injectors deliver the precise fueling needed to support demanding gasoline and E85 combinations while maintaining excellent idle quality and throttle response.
Constructed with a durable stainless alloy valve, the IS801-1440H is compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Every injector is individually flow tested, dynamically matched, and serial numbered using Fuel Injector Clinic's proprietary Data Match Technology, with a detailed Data Match Sheet included for precise ECU calibration. Flow testing is performed at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit. PGTUSC6 injector pigtails are included for installation, while optional PADPUtoJ6 Plug and Play adapters are available separately for a no-cut installation. Every injector set includes all required O-rings for the factory application and is backed by Fuel Injector Clinic's Lifetime Warranty against defects in original manufacture.
