These high-quality 5-ply silicone couplers are fiber-reinforced to maintain their shape under high boost while still providing the flexibility needed to isolate your TMIC from engine movement and vibration. Each kit includes a 90° turbo outlet coupler, throttle body coupler, and a full set of stainless steel Breeze high-torque clamps for a secure, leak-free installation.
