Show original supplier description
The MAPerformance EVO X 93oct 400whp+ [500whp+ E85] Fuel Upgrade Kit is designed to address limitations in the factory fuel system for those seeking increased horsepower. This kit provides all necessary components to upgrade your Evo X's fuel delivery capabilities, supporting up to 400 wheel horsepower on 93 octane fuel and up to 500 wheel horsepower on E85. The kit features ID1050x injectors, which are motorsport-grade and built to specific parameters for optimal performance and driveability. These injectors are the result of a partnership between Injector Dynamics and Bosch Motorsport. Complementing the injectors is a MAP inline fuel filter with a 40-micron stainless steel element, designed to protect the injectors from debris and ensure proper fuel flow, compatible with both pump gas and E85. The kit also includes the industry-standard Walbro 255lph GSS342G3 fuel pump, capable of supporting up to 500whp on E85 configurations. Benefits of this upgrade include compatibility with all fuels, increased fuel flow capacity to match other performance modifications, and enhanced fuel filtration to maintain injector health. The package includes ID1050X Injectors with plug-and-play adapters, a MAP EVO X Inline Fuel Filter Kit, a MAP EVO X Fuel Pump Install Kit for the Walbro 255, and the Walbro 255lph High Pressure Fuel Pump. Fuel rails are not included but can be added separately. This product is not CARB legal.
