The Precision Raceworks B58 Port Injection Kit with flex fuel compatibility is a necessity to safely and sufficiently support the power levels anyone needing additional fueling. This kit is capable of providing supplemental fueling to all BMW's equipped with the B58 engine (Gen1 and Gen2) (see fitment guide for full details).

The complete kit integrates seamlessly into your car like it left from the factory with it installed; you can barely even see the kit once the car is assembled! This kit includes everything needed to add multi-port injection and is 100% e85 compliant. We include new genuine Bosch Motorsport injectors which are flow matched both static and dynamic. A Detailed certificate of conformance included with each kit giving you all flow data needed for optimal tuning.

Don’t be tricked into thinking all port injection kits are equal, the Precision Raceworks is the only port injection kit currently where all 6 injectors have even fuel distribution for each cylinder. Additionally this kit features 750cc* injectors standard (this flow rate is based on industry injector flow test pressure of 43.5psi) at 72psi these injectors flow 1000cc. What this means is our kit is capable of supporting builds from 400whp up to 1,000whp out of the box.

Simply pick up this kit and pair it with your favorite injector controller!  We have several to choose from:

ReFlex Lite - Simple controller that is similar to the AIC in price, but gives you Seqential fire of your injectors.  This improves fuel trims, fuel pressures are more stable, and each injector will output more fuel each time it fires.

ReFlex Plus - Advanced controller featuring CanBus integration, ability to add an ethanol sensor and integrate a true flex fuel tune, ability to add a fuel pressure sensor, and additional capabilites.

*Actual flow rate may vary, as advertised flow rate is common average.
