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.

Installation Instructions
  • Motorsport-grade Bosch EV14 injectors deliver the fuel capacity real Stage 3+ power demands, 980cc/min each in a four-injector set (0280 158 040)
  • 30° single cone spray angle, 0° bent/gamma angle, 24mm extended-tip nozzle, and 33.6mm compact body for precise atomization in tight quarters
  • Requires matching APR Stage 3+ ECU software to operate, the fueling backbone behind every Stage 3+ Golf R, S3, and TT/TTS build
  • APR fuel distribution block included, everything needed to feed all four injectors from stock fuel lines
  • OEM-style fuel rail, rail sensor, and mounting hardware included for a clean, factory-fit install
  • Top-feed design with 12 ohm coil resistance for reliable, OEM-level electrical compatibility
  • E85 and M100 compatible for maximum power potential on high-octane and flex-fuel builds
  • Supports up to 8 bar of fuel pressure for aggressive motorsport-level tunes
