What do I need to run Port Injection on my VW/Audi?

To add port injection to your EA888.3 motor, all you need is one of our MPI kits and an upgraded LPFP with upgraded fuel lines!


As for the MPI kits, in addition to choosing the injector size, we offer this in two variants. 

  1. Standard Kit - This kit is for all EA888.3 motors without factory port injection
  2. ROW Kit - This kit is specific for customers that already have factory MPI (outside of the USA only), and wish to upgrade the injectors and fuel rail.



Now for the B8/B8.5, the port injection kit we offer fully replaces the intake runners between the supercharger and the head.  This does necessitate custom tuning as the intake runner flaps are deleted in this process.  Additionally, you will need a port injection controller such as the Reflex Lite, as these cars do not have any accommodation for MPI from the factory.
