Description
Real Stage 3+ power lives or dies on fuel delivery, and the APR Multi-Port Injection (MPI) System is the difference between a turbo that flows and an engine that starves. Built around four Bosch Motorsport EV14 980cc/min injectors, this system supplements the factory direct-injection fuel system with high-flow port injection, delivering the fuel volume needed to safely support Stage 3+ boost, E85, and M100 calibrations that the stock fuel system simply can't keep up with.
