Fuel Injector Clinic 525cc High Impedance Fuel Injector Set (IS801-0525H) - 2000-2006 BMW E46 M3 / 2006-2008 BMW Z4 M
Upgrade the fuel system in your BMW with the Fuel Injector Clinic IS801-0525H Fuel Injector Set. Designed for the legendary S54-powered BMW E46 M3 and BMW Z4 M, this complete set of six 525cc saturated (high impedance) ball and seat injectors delivers the precision fueling needed for naturally aspirated performance builds as well as mild forced induction applications. Utilizing the latest injector technology, these injectors provide exceptional linearity, precise fuel metering, and outstanding short pulse width repeatability for smooth idle quality, crisp throttle response, and excellent drivability.
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, giving tuners the information needed for accurate ECU calibration and balanced cylinder-to-cylinder fueling. The injectors are flow tested at 43.5 PSI (3 Bar) using CF-16B calibration fluid at 90 degrees Fahrenheit and include all required O-rings for the factory application. PGTUSC6 injector pigtails are included, while optional PADPUtoJ6 Plug and Play adapters are available for customers who prefer not to modify the factory wiring harness. Every injector set is backed by Fuel Injector Clinic's Lifetime Warranty against defects in original manufacture.

FAQs
Do these injectors require wiring modifications?
Yes. The IS801-0525H includes PGTUSC6 injector pigtails for solder-in installation. If you prefer not to cut or solder the factory harness, optional PADPUtoJ6 Plug and Play adapters are available separately.
Why are injector pigtails included?
Fuel Injector Clinic supplies brand-new injectors rather than remanufactured or core-based injectors to maximize reliability and consistency. The included pigtails or optional Plug and Play adapters provide the flexibility to install these injectors while maintaining the benefits of brand-new components.
