Torque Solution Phenolic Thermal Intake Spacers 3mm (TS-SU-478-3) fit Subaru EJ25 turbo engines in WRX STI Forester XT Legacy GT and Impreza models from 2002 to 2020.

  • CNC Machined: Precision fit for EJ engines requires no modifications or adapters
  • Hardware Included: Reinforced black oxide coated stainless steel bolts and washers resist corrosion
  • Performance Results: Typical 5-15 HP gains improved throttle response reduced heat soak

Product Notes
