Audi A3 Fueling Kit - APR - Stage 3+ MPI & LPFP - 2017–2019. A proven fueling solution for EA888 Gen 3 A3 models that delivers the headroom needed to support APR Stage 3+ power levels.

This comprehensive upgrade adds four 980 cc Bosch Motorsport ethanol-compatible MPI injectors to work alongside the factory GDI system and replaces the in-tank low-pressure fuel pump with a high-flow 305 LPH unit. APR integrates added sensors and calibration so the factory ECU maintains closed-loop control of both injection systems. Included plug-in harnesses, distribution block, and mounting hardware make integration straightforward while port injection helps keep intake valves cleaner over time.

Features

• 980 cc Bosch Motorsport MPI injectors (ethanol compatible)
• 305 LPH in-tank LPFP; factory basket and PWM controller compatible
• APR ECU strategy with added sensors for closed-loop control
• Fuel distribution block for proper MPI/GDI delivery
• Port injection helps reduce intake valve deposits
• For NAR A3 without factory MPI; appropriate software required
