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.


  • 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


  • 2004-20 Subaru Impreza STI (w/ factory or GrimmSpeed TMIC only)
  • 2002-07 Subaru Impreza WRX (w/ STI or GrimmSpeed TMIC only)
  • 2004-08 Subaru Forester XT (w/ STI or GrimmSpeed TMIC only)

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. 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!

Solid hoses (requires trimming)

A bit of trimming required on turbo hose to fit stock TMIC. If you don’t, good luck installing that intercooler. Lol.
Great hoses otherwise.


Thank you for sharing your experience with the Grimmspeed Top Mount Intercooler Silicone Coupler Kit. It is important for potential buyers to know about any modifications or adjustments that might be necessary during installation. It is good to hear that the hoses worked well once they were properly trimmed and installed. Your insights are valuable for others who might be considering the same product for their vehicles.

I Ducked Up :D

So the throttle one was easy to mount. The one that goes to the turbo I Dcuked up... I cutted it to short, I guess I didnt do the proper research on how much to cut. I would love for these to come pre-cut (idiot proof like me) any ways I order a couple more. Quality is amazing !


Thank you for your 5 Star Review of the Grimmspeed Top Mount Intercooler Silicone Coupler Kit! Sometimes mistakes are made, it happens!


Perfect Fit

This coupler worked perfectly with the GrimmSpeed TMIC upgrade for a 2016 STi.


Thank you for your 5 Star review! The GrimmSpeed coupler is a perfect way to finish off the GrimmSpeed TMIC upgrade!
