Audi S3 Fueling Kit – APR Stage 3+ MPI & LPFP (2015–2020). A complete fuel-system upgrade that adds the headroom required for APR Stage 3+ on the 2.0T EA888 Gen 3.

APR calibration enables the factory ECU to run both GDI and added MPI with accurate closed-loop control. The kit includes hardware, sensors, distribution block, fuel rail, and plug-and-play harnesses. Four ethanol-compatible 980cc Bosch Motorsport MPI injectors pair with a 305 LPH in-tank LPFP compatible with the OEM PWM controller. Port injection also helps limit intake-valve buildup on direct-injected engines. Requires appropriate software; designed for North American vehicles originally without factory MPI.

• Factory ECU control of dual GDI/MPI (APR ECU software required)
• 305 LPH ethanol-compatible in-tank LPFP
• Four 980cc Bosch Motorsport MPI injectors
