Take your S54-powered BMW to the next level with the Fuel Injector Clinic IS801-1650H Fuel Injector Set. Designed for the 2000-2006 BMW E46 M3 and 2006-2008 BMW Z4 M, this complete set of six 1650cc saturated (high impedance) ball and seat injectors delivers the massive fuel capacity required for serious forced induction and high-horsepower engine combinations while maintaining exceptional idle quality and street drivability. Built with the latest injector technology, these injectors provide outstanding linearity, excellent short pulse width control, and consistent fuel delivery across the entire operating range.
The IS801-1650H represents Fuel Injector Clinic's largest high impedance injector compatible with all race fuels. Thanks to its stainless alloy valve construction, it is compatible with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels without sacrificing reliability. 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. Each injector is flow tested at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit, includes all required O-rings for installation, features a true Plug and Play fit to the factory wiring harness, and is backed by Fuel Injector Clinic's Lifetime Warranty against defects in original manufacture.
