High Quality Replacement TMIC Y-Pipe Hoses

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!

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