Feed your high-performance BMW E30 M3 with the fueling precision it deserves using the Fuel Injector Clinic IS803-1000H Fuel Injector Set. This complete set of four 1000cc saturated (high impedance) ball and seat injectors is engineered specifically for the legendary E30 M3 and provides the fuel delivery needed for serious naturally aspirated, turbocharged, and supercharged combinations. Utilizing the latest injector technology, these injectors deliver exceptional linearity, superior short pulse width control, and outstanding drivability from idle through full throttle, making them an excellent choice for demanding street and race applications.
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 with individual flow and latency values, providing tuners with the accurate data needed for consistent ECU calibration. The injectors are flow tested at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit, include all required O-rings for the factory application, and are backed by Fuel Injector Clinic's Lifetime Warranty against manufacturing defects. PGTUSC4 injector pigtails are included, while optional PADPUtoJ4 Plug and Play adapters are available for installers who prefer not to modify the factory wiring harness.
