Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set (IS803-2150H) - 1986-1991 BMW E30 M3
When maximum fuel delivery is the priority, the Fuel Injector Clinic IS803-2150H Fuel Injector Set is built to deliver. This complete set of four 2150cc saturated (high impedance) injectors is designed for the most demanding high-horsepower BMW E30 M3 builds where extreme fuel flow is required without giving up low-speed drivability. Utilizing the latest injector technology, these are the largest high impedance injectors offered by Fuel Injector Clinic and feature exceptional short pulse width control that helps deliver smooth idle quality and predictable part-throttle operation despite their enormous flow capacity.
To achieve this level of performance, every injector is dynamically matched using Fuel Injector Clinic's proprietary Data Match Technology. Each injector is individually flow tested, serial numbered, and supplied with a comprehensive Data Match Sheet containing detailed flow and latency values for accurate ECU calibration. 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. PGTDEN4 injector pigtails are included, while optional PADPDtoJ4 Plug and Play adapters are available for installers 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.

Important Fuel Compatibility Information
The IS803-2150H utilizes an internal seal that can swell when exposed to MTBE oxygenated fuels. Do not use these injectors with VP Q16, VP Import, or any other MTBE oxygenated fuel. This swelling can significantly reduce injector flow and negatively affect engine performance.
These injectors are compatible with gasoline, E85, and other non-MTBE fuels. If operating with alcohol-based fuels such as E85, Fuel Injector Clinic recommends following proper storage and maintenance procedures to help prevent corrosion during extended periods of inactivity.

FAQs
Do these injectors require wiring modifications?
Yes. The IS803-2150H includes PGTDEN4 injector pigtails that can be soldered into the factory wiring harness. If you prefer a no-cut installation, optional PADPDtoJ4 Plug and Play adapters are available separately.
Can these injectors be used with VP Q16 or VP Import fuel?
No. The IS803-2150H should not be used with VP Q16, VP Import, or any other MTBE oxygenated fuel because the internal seal can swell and significantly reduce injector flow.
