Fuel Injector Clinic 2150cc High Impedance Fuel Injector Set for BMW S58 M2, M3 & M4 (IS833-2150H)
When your BMW S58 build demands maximum fuel delivery, the Fuel Injector Clinic IS833-2150H 2150cc High Impedance Fuel Injector Set is engineered to deliver. Designed specifically for S58 applications utilizing an aftermarket intake manifold or port injection kit, this six-injector package provides the massive flow capacity needed for extreme horsepower builds while maintaining impressive idle quality and drivability. Whether you're building a dedicated drag car, roll racing machine, or high-output E85 setup, these injectors deliver the precision and consistency serious tuners expect.
Built around advanced high impedance ball and seat injector technology, the IS833-2150H features exceptional linearity and outstanding short pulse width repeatability. Fuel Injector Clinic utilizes its exclusive Data Match Technology to dynamically flow match every injector, significantly improving ECU control during idle and part-throttle operation where pulse widths are typically below 2 milliseconds. Each injector is individually serial numbered and supplied with a detailed calibration sheet containing injector-specific flow and latency data for the highest level of tuning accuracy.

Important Fuel Compatibility Information
Do NOT use these injectors with MTBE oxygenated race fuels such as Q16 or VP Import. The internal seal used in the 2150cc injector has been found to swell when exposed to MTBE, which can significantly reduce injector flow. If running alcohol-based fuels such as E85, Fuel Injector Clinic recommends following proper injector care procedures to help prevent corrosion during extended periods of storage or disuse.

FAQs
Can these injectors be used with Q16 or VP Import race fuel?
No. Fuel Injector Clinic specifically advises against using the IS833-2150H with MTBE oxygenated fuels such as Q16 or VP Import because the internal seal can swell, reducing injector flow and performance.
Why are these injectors easier to tune than many other large injectors?
Fuel Injector Clinic dynamically matches every injector using proprietary Data Match Technology, dramatically improving consistency at idle and part throttle where extremely short pulse widths are required. This results in better drivability and more predictable ECU calibration.
