The Black Market Parts Multi-port Injection (MPI) kit with flex fuel capability is a necessity to safely and sufficiently support the power levels of upgraded turbos. This kit is capable of supporting all BMW’s with N54 and N55 engines with supplemental fueling.

This kit integrates seamlessly into your car like it left from the factory with it installed; you can’t 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 is 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 BMP kit is the industry leader. 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 and anywhere in between!

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

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

(Use of supplemental injector controller is required)

*Actual flow rate may vary, as the advertised rate is based upon an overall average.
