Description
The Unitronic MPI Fuel Rail Upgrade Kit is the most complete, plug-and-play solution for adding multi-port injection (MPI) to the factory 2.0TSI EA888 EVO4 intake manifold. Specifically engineered for the MK8 Golf R, 8Y Audi S3, and MK8 GTI, this system delivers the fuel capacity required to maximize performance while maintaining safety, particularly when running high-ethanol blends such as Stage 3 E85 applications.
Every component has been carefully designed, precision-manufactured, and rigorously tested by Unitronic to ensure OEM-level fitment, reliability, and performance. At its core is a CNC-machined billet aluminum fuel rail, paired with Genuine Bosch Motorsport 980cc fuel injectors and a Bosch Motorsport fuel pressure sensor, ensuring consistent and precise fuel delivery under high-performance conditions.
Premium fuel lines, pinch clamps, and installation hardware are included, along with a plug-and-play wiring harness for seamless integration. To further simplify installation, Unitronic provides a precision drill bit and guide for preparing the OEM intake manifold. The result is a complete, professional-grade MPI system designed to meet the fueling demands of today’s most aggressive builds.
