GrimmSpeed Top Mount Intercooler Silicone Hose Kit – 02-07 WRX / 04-21 STI

GrimmSpeed Top Mount Intercooler Silicone Hose Kit – 02-07 WRX / 04-21 STI


Is your old 90 degree 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? We have the solution!




High-quality replacement TMIC Y-Pipe Hoses.

Special Fitment Note: Supported fitments include only those vehicles running OEM STI and GrimmSpeed Top Mount Intercoolers. The elbow coupler is sized to fit multiple turbo setups, some trimming may be required.


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 90deg turbo outlet coupler, throttle body coupler and stainless steel BREEZE high-torque clamps.

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
