2008-2015 Mitsubishi Evo X E85 Fuel System For 500whp by MAPerformance

In the hunt for horsepower, few things will stop you in your tracks more abruptly than an ill prepared fuel system. The MAPERFORMANCE 500whp Fuel system kit consists of quality components from industry leading manufacturers, and will be everything you need to take the next step with your Evo X.

The Injector Dynamics ID1300X fuel injectors are an all new injector, designed in partnership with Bosch Motorsport. This collaboration has given them the ability to design a high flow injector with characteristics specific to the needs of the motorsport tuner. The ID1300 was designed with alternative fuels in mind, and is the only performance injector available with all stainless internals. It is compatible with all known fuels, and will stand up to the corrosive nature of alcohol better than any injector on the market. The ID1300 injectors were designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300 has a minimum fuel mass compatible with gasoline use, and will provide exceptional idle and cruise behavior under these conditions.

The MAP inline fuel filter was developed as a solution to protect your fuel injectors from debris and potentially even save your engine from a clogged fuel injector. Located between the hard factory feed line and the fuel rail installation couldn't be simpler with the push-on EFI adapter fittings. The compact billet fuel filter features a 40 micron stainless steel element that is compatible with both pump gas and E85, and flows enough to support nearly 500lph.

The Walbro 450lph pump has been the industry standard for many years.  Included in every kit is an authentic Walbro fuel pump that is compatible with E85 and pump gas and good for up to 500whp on most E85 configurations.


  • Includes everything needed to upgrade your fuel system for 500whp on E85 and 500whp on 93oct
  • Motorsport grade injectors for maximum power and driveability in all conditions
  • External Fuel filter to replace removed factory unit with pump install

Please Note:

MAP 500 WHP Kit

Kit fit great!

Make sure to get an AFPR and/or drill your venturi!


Great kit. Be sure to install fuel pump the correct way and be sure to avoid any kinks in the hose to avoid any lean conditions, also your tuner may want you to hardwire this. I used the deatschwerk hardwire kit

MAPerformance Fuel Kit FTW

MAPerformance has made it easy to upgrade your fuel system by coming up with this kit. Don't forget to bundle it up with upgraded fuel rail and fuel pulse damper
