Description
The Unitronic MPI Fuel Rail Upgrade Kit for MQB EA888.3 is a complete plug-and-play solution designed to add port-side fuel injectors to your North American intake manifold. Engineered for high-performance MK7 Golf, GTI, GLI, Golf R, and 8V.2 A3/S3 vehicles, this kit ensures increased fuel delivery, optimized power output, and reliable track performance.
At the heart of this upgrade is Unitronic’s CNC-machined billet aluminum fuel rail, constructed from 6061-T6 aluminum with a hard anodized black finish for durability and ethanol resistance. This rail works seamlessly with Bosch Motorsport 980cc EV14 fuel injectors, providing superior flow and performance for high-boost applications. A Bosch fuel pressure sensor and genuine Continental ethanol content sensor are included for accurate fuel monitoring, while premium fuel lines and pinch clamps guarantee leak-free operation.
Designed for simplicity, the kit includes a plug-and-play wiring harness, a precision drill bit and guide for intake manifold preparation, and all required installation hardware. While this kit works with OEM ECUs, MPI-specific tuning is required to unlock its full potential.
