MPI Fueling Kit

The MPI System is the hardware half of APR's Stage 3+ ecosystem, required alongside matching APR ECU/TCU software to unlock true Stage 3+ output. If you're already running APR Stage 3 software and looking to add the fueling capacity to go further, or building a custom Stage 3+ setup piece by piece, this is the component that makes it possible. Compatible across the EA888 Gen 3 (Audi 8V/8Y A3, S3, TT, TTS, Q3; VW Mk7/Mk7.5 Golf R, GTI, Arteon, Jetta) and EA888 Gen 4 (2022+ Mk8 Golf R, Audi S3) platforms.
