GrimmSpeed Top Mount Intercooler Silicone Hose Kit 2002-2007 WRX / 2004+ STI

  • Is your old 90 degree top-mounted intercooler (TMIC) coupler all chewed up from years of use? Is it dirty and oil-covered? Looking to just add a bit of color to your engine bay? GrimmSpeed has the solution!

    Quick Specs

    • 5-Ply High-Grade Silicone Couplers - Smooth interior to maximize airflow and minimize restriction
    • Heat Resistant Reinforcement - Couplers keep their shape, even at high boost levels
    • Trim-to-fit Geometry - The turbo leg of the 90 degree coupler is intentionally long for fitment with older, smaller turbos
    • Stainless Steel High-Torque Clamps - Rust-proof construction with smooth operation

    These 5-ply silicone couplers are fiber-reinforced to prevent distortion in high boost scenarios but offer mobility and flexibility, isolating your TMIC assembly from the vibrations of your engine. All kits come with a replacement 90-degree turbo outlet elbow coupler, a throttle body coupler, and stainless steel Breeze high-torque clamps.

    Note that this kit requires a cast metal intercooler Y-pipe, which is not included. If you have a WRX or Forester XT with the stock single-piece rubber/plastic Y-pipe/turbo outlet elbow, this kit will NOT fit.

    Select black or red coupler color.
