Product Description

The Fuel Injector Clinic (FIC) IS833-1650H injector set is a high-flow, high-impedance fueling solution engineered to support significantly increased horsepower and performance for compatible high-output engines — most notably BMW S58 platforms (e.g., M2/M3/M4 G80/G82/G87) and other engines with similar requirements when used with appropriate harness/pigtails. These 1650 cc/min injectors utilize advanced Data Match Technology for precise flow and latency matching, enhancing drivability, tuning accuracy, and fuel delivery consistency under high load. Built for vehicles running elevated power levels on gasoline, E85, or other race fuels, this injector set helps you sustain richer mixtures safely, accelerating turbo response and extending safe performance limits.

Fitment Notes

  • Designed primarily for BMW M2, M3, M4 (G80/G82/G87) S58 engines with aftermarket intake manifolds or port injection setups.

  • Ideal for high-output builds requiring >1000 cc fuel flow per injector. 

  • Includes necessary o-rings for proper fitment; verify connector type and wiring harness compatibility prior to ordering. 

  • Professional tuning and fuel system calibration required when upgrading to high-flow injectors.
