Description

The Black Market Parts (BMP) Multi-port Injection (MPI) kit with flex fuel capability is essential for safely supporting the power output of upgraded turbos on BMW N54 and N55 engines. This kit integrates seamlessly, appearing as a factory-installed component. It includes everything necessary to add multi-port injection and is fully compliant with E85 fuel. The kit comes with genuine Bosch Motorsport injectors that are meticulously flow-matched, both statically and dynamically, ensuring precision fueling. A detailed certificate of conformance is provided, containing all necessary flow data for optimal tuning. The standard 750cc injectors (rated at 43.5psi) can flow up to 1000cc at 72psi, enabling the kit to support builds ranging from 400whp to 1,000whp. Use of a supplemental injector controller is required with this kit. Compatible controller options include the ReFlex Lite, which offers sequential injector firing for improved fuel trims and stability, and the ReFlex Plus, an advanced controller with CANbus integration for F-series cars, ethanol sensor capability, and a true flex fuel tune. The kit includes stainless OEM-style studs and OEM spec manifold gaskets for the port injection plate.
