Show original supplier description

The MAPerformance EVO X E85 Fuel Upgrade Kit is designed to meet the fuel demands of high-performance Mitsubishi Lancer Evolution X models from 2008 to 2015. This kit enables users to achieve substantial power gains, supporting over 400 horsepower on E85 and over 500 horsepower on 93-octane fuel. It's an essential upgrade for those increasing boost pressure or modifying their engine for higher output. The kit features ID1050x injectors, which are built to motorsport specifications for optimized performance and response, even at low flow rates. It also includes a compact billet inline fuel filter with a 40-micron stainless steel element to protect the injectors from debris and ensure compatibility with both pump gas and E85. A high-performance Walbro 450 LPH fuel pump is also included, known for its reliability and ability to deliver ample fuel for engines exceeding 500 HP on E85. Installation of this kit requires modifications to the vehicle's wiring, fuel lines, and fuel module. Professional installation is recommended to ensure proper setup and safety. Additionally, while the injectors and fuel pump are included, the fuel rails are not part of this kit and must be purchased separately; customers can select their preferred fuel rail from the available options.
