In the hunt for horsepower, few things will stop you in your tracks more abruptly than an ill prepared fuel system. The MAPERFORMANCE 400whp 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 ID1050x injector is the evolution of the ID1000, and the latest addition to the X-Series. It is the most recent offering from the partnership of Injector Dynamics and Bosch Motorsport, and is the result of lessons learned during the development of the ID1300x, and ID1700x. Like the ID1300x and ID1700x, the ID1050x is not a modified production component. It is a built to spec motorsport injector, offering optimization of critical operating parameters important to you, the motorsport tuner.

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 255lph GSS342 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 400whp on most E85 configurations.


  • Includes everything needed to upgrade your fuel system for 400whp 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


  • Compatible with all fuels
  • Increased fuel flow capacity to match other bolt on upgrades
  • Increased fuel filtration to help keep the injectors in the best working condition

Please Note:

  • Fuel Rail are not included but can be added at an addition cost by selecting a fuel rail of choice from drop down menu.
