High horsepower configurations often require more fuel, especially on applications where ethanol is used. The APR 980cc MPI Injector Upgrade Kit includes an upgraded high-flow multiport injection (MPI) injector and harness necessary to satisfy high horsepower builds. The kit uses a compact and extended tip Bosch EV 14 injector that supports Ethanol and Methanol and flows 980cc/min at 3 bar. A high quality 2 wire harness with braided wire sheathing converts the Bosch Jetronic connector to the necessary factory style connector making this upgrade plug-and-play with an associated ECU upgrade. Fits Audi RS3 17-24, TT RS Quattro 18-22
