Precision Raceworks BMW B58 Engine Port Injection Kit (F Series & G Series)

The Precision Raceworks B58 Port Injection kit with flex fuel compatibility is a necessity to safely and sufficiently support the power levels of anyone needing additional fueling. This kit is capable of providing supplemental fueling to all BMWs 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. This means the Precision Raceworks kit is capable of supporting builds from 400whp up to 1,000whp out of the box.
