Adding port injection is a fantastic and effective method of increasing power, and it's potential is effectively unlimited!


To add port injection you will need a few things.

  1. Port injection plate or aftermarket intake manifold with port injection accommodations.
    • We offer Plate kits for N54, N55, S55 and B58
    • S58 we offer a fuel rail that mounts directly to the factory intake manifold with some modifications
    • Alternatively there are many aftermarket manifolds available for each of these cars that include a fuel rail for port injection.  These may be AN8 or AN6 ends, and we will need to know this to ensure you have any necessary adapters.
  2. Port injection controller
    • For this we offer two options.  Reflex + and Reflex Lite.
    • Generally we recommend the Reflex+ due to it's CanBus integration and additional capabilities on most platforms.
  3. Upgraded LPFP (low pressure fuel pump)
    • We offer various options for each of the vehicles, and your ultimate power goals will dictate which one we recommend for you!
