Searching for a top - notch replacement TMIC Y - Pipe Hose kit for your 2002 - 2007 Subaru WRX and 2004 - 2021 STI? Your search ends here! If your old 90 - degree TMIC coupler is worn out, dirty, and oil - covered, or if you just want to add some color to your engine bay, we've got the perfect solution. Our kit features 5 - ply high - grade silicone couplers with a smooth interior to boost airflow and reduce restrictions. The heat - resistant reinforcement ensures the couplers keep their shape even under high boost. The turbo leg of the 90 - degree coupler is long, fitting older, smaller turbos. It comes with stainless - steel high - torque clamps that are rust - proof and operate smoothly. These fiber - reinforced 5 - ply silicone couplers prevent distortion in high - boost situations while offering flexibility, isolating the TMIC assembly from engine vibrations. All kits include replacement 90 - degree turbo outlet couplers, throttle body couplers, and BREEZE high - torque clamps. Fitment includes 04 - 21 Subaru Impreza STI (with factory or GrimmSpeed TMIC only), 02 - 07 Subaru Impreza WRX (with STI or GrimmSpeed TMIC only), and 04 - 08 Subaru Forester XT (with STI or GrimmSpeed TMIC only). Note that supported vehicles must run OEM STI or GrimmSpeed Top Mount Intercoolers, and some trimming of the elbow coupler may be needed for certain turbo setups.
Using this Grimmspeed silicone hose kit is easy. First, make sure your vehicle is turned off and cooled down. Remove the old TMIC Y - Pipe Hose and the 90 - degree coupler. Install the new 5 - ply silicone couplers in place and secure them with the stainless - steel high - torque clamps. Check the fitment carefully and trim the turbo leg of the 90 - degree coupler if necessary to fit your turbo setup. When using your vehicle, keep in mind that the kit is designed for vehicles with OEM STI or GrimmSpeed Top Mount Intercoolers. For maintenance, regularly inspect the couplers and clamps for any signs of wear or damage. If the couplers get dirty, you can clean them with a mild soap and water solution. Make sure to dry them thoroughly before reinstalling. If you notice any issues like air leaks or loose clamps, tighten the clamps or replace the couplers as needed.
