Custom ECU Tuning is required to activate and utilize this kit 


Introducing EQT's Multi-Port Injection supplemental fueling kit. When upgrading your EA888.3 equipped MQB car, the stock fueling becomes a limitation with increased demand. The factory direct injectors are a weak point, reaching saturation even on upgraded high pressure fuel pumps. By adding a second injector per cylinder into your North American Region intake manifold to accompany your direct injector, you gain all the fueling necessary to support any horsepower goal you have. Our in house manufactured and designed kit integrates seamlessly into your factory ECU to provide a factory-like fit and finish.

Key Features: 

  • Proprietary billet aluminum fuel rail made in house in the U.S.A. 
  • Every set of injectors is flow matched and balanced 
  • High end complete wiring harness with oil and heat resistant coverings
  • Single fusible link for entire harness, no need for multiple fuse locations in factory fusebox 
  • Tooling included to convert non-MPI manifolds 
  • Easy factory-like ECU integration  
  • Ethanol content wiring is included into our harness (Sensor not included) 
  • OEM Bosch sensor included  
  • Eliminates the need to clean intake valves
