Fuel Injector Clinic 1200cc High Impedance Fuel Injector Set (IS803-1200H) - 1986-1991 BMW E30 M3
Take the fuel system in your BMW E30 M3 to the next level with the Fuel Injector Clinic IS803-1200H Fuel Injector Set. This complete set of four 1200cc saturated (high impedance) ball and seat injectors is engineered for enthusiasts pushing the limits of their naturally aspirated, turbocharged, or supercharged S14 engine. Utilizing the latest injector technology, these injectors provide outstanding linearity, exceptional short pulse width control, and consistent fuel delivery for smooth drivability and simplified tuning from idle to wide open throttle.
Every injector is individually flow tested, matched, and serial numbered using Fuel Injector Clinic's proprietary Data Match Technology. Each matched set includes a detailed Data Match Sheet containing individual flow and latency values for precise ECU calibration and consistent cylinder-to-cylinder fueling. The IS803-1200H is a true Plug and Play fit for the OEM wiring harness, eliminating the need for wiring modifications. Previously sold as IS803-1100H, this updated injector set is flow tested at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit, includes all required O-rings for the factory application, and is backed by Fuel Injector Clinic's Lifetime Warranty against defects in original manufacture.
