The Ecotune MQB Port Injector Upgrade is the definitive solution for vehicles reaching the flow limits of the factory fueling system. Designed for the EA888 Gen 3 engine, this kit adds high-capacity port injection to complement the factory direct injection. This is a critical requirement for high-horsepower Stage 3 builds and any vehicle running high ethanol blends (E85), ensuring the engine receives precise fuel delivery without overstressing the injectors.

Key Features & Benefits
- Increased Fuel Ceiling: Provides the necessary flow to support high-output turbochargers and aggressive E85 tuning profiles.
- Plug-and-Play Wiring: Includes a bespoke, high-quality wiring loom that integrates seamlessly with the factory ECU and Reflex hardware.
- Optimized Atomization: Features high-quality injectors selected for their superior spray pattern, ensuring efficient combustion and idle stability.
- Flex Fuel Ready: Specifically designed to work in conjunction with Flex Fuel kits to manage the 30% increase in fuel volume required by ethanol.
- Motorsport Reliability: Components are tested to withstand the high temperatures and pressures of a performance engine bay.
Professional Installation & Tuning
The installation of port injectors and wiring looms requires technical expertise to ensure a leak-free seal and correct electrical pinouts.
- Expert Workshop Fitting: We offer professional installation and leak testing at our MGM Leeds Workshop.
