High Flow Direct Injection Fuel Injector Upgrade Focus RS/ST

  • 2016-2018 Ford Focus RS
  • 2013-2018 Focus ST
  • 2.0L Ford EcoBoost
  • 2.3L Ford EcoBoost

After 2 years in testing and development, we are now pleased to announce the availability of upgraded high flow fuel injectors for the 2.3L and 2.0L EcoBoost. Xtreme-DI along with the Mountune Engineering team have logged hundreds of hours of testing on engine and chassis dynos and thousands of miles of test cycles to ensuring durability resulting in a reliable injector upgrade for the 2.3L EcoBoost with a 50% increase in flow rate. These components power the fastest and most powerful Focus RS’s in the world.
These injectors are only compatible with an upgraded high pressure fuel pump.
