Show original supplier description
The Cobb Tuning Fuel Pressure Regulator Kit is a direct-fit upgrade for 2008-2021 Subaru WRX STI models equipped with the EJ257 engine. This comprehensive kit allows for adjustable base fuel pressure, ensuring optimal fuel delivery when using different injector and fuel pump combinations. The kit includes the fuel pressure regulator, all necessary mounting hardware, fuel lines, and fittings. It also incorporates a manifold reference relocation kit for a streamlined setup. For enhanced monitoring, it is compatible with the Cobb fuel pressure sensor and the Accessport for real-time rail pressure readings. This kit is multi-fuel compatible and suitable for use with Stage 3 OTS Maps, but custom tuning is required for other setups. Attention is specifically called to the necessity of custom tuning to properly utilize this fuel pressure regulator kit.
