APR Fueling System Upgrade MQB - Stage 3
The APR Fueling System is a comprehensive upgrade required to safely support Stage III+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold, both of which are ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR’s ECU Upgrade.
More Fuel and More Power
Provides the required fueling to support APR Stage III+ power levels.
980 CC Bosch Motorsport MPI Injectors
Converts the factory injection system to a true, dual, MPI and GDI setup, with large enough injectors to support power levels well beyond APR Stage III+ power levels.
305 LPH High Flow In-Tank Fuel Pump
Upgrades the LPFP to the largest readily available pump compatible with the factory fuel basket, and PWM controller without additional controllers.
APR Stage III+ ECU Upgrade
Upgrades Stage III to III+ with the necessary and complex ECU calibration changes necessary for accurate, closed-loop control of the fueling system, without the need for risky ECU tricks or external controllers.
Proper MPI/GDI Fuel Distribution
The fuel distribution block ensures fuel is properly delivered to the both sets of injectors.
Ethanol Compatible Hardware
Fully Ethanol / E85 compatible injectors, fuel pump and associated hardware.
Cleaner Intake Valves
Performance-robbing buildup on the intake valves, a common byproduct of gasoline direct injected (GDI) engines, is greatly reduced through the cleaning effect associated with port injection.
Mounting Hardware, Directions and Support
Includes step-by-step instructions and support to for a seamless install with the included plug-and-play wiring harnesses, sensors, mounting hardware, fuel rail, and more!
