5-Ply Silicone Coupler Kit

These 5-ply silicone couplers are engineered with a smooth interior to optimize airflow and reduce restriction, ensuring efficient performance. The heat-resistant reinforcement helps the couplers maintain their shape even under high boost conditions, preventing distortion and maintaining integrity. The kit includes a replacement 90-degree turbo outlet coupler with a trim-to-fit geometry, intentionally made long to accommodate older, smaller turbos. It also includes a throttle body coupler and rust-proof, smooth-operating stainless steel BREEZE high-torque clamps. The fiber-reinforced construction offers both flexibility and durability, isolating the TMIC assembly from engine vibrations. This coupler kit is designed for specific Subaru Impreza STI (2004-2020) and WRX (2002-2007) models, as well as the Subaru Forester XT (2004-2008). A critical fitment note specifies that these hoses are intended for vehicles equipped with either a factory STI intercooler or a GrimmSpeed Top Mount Intercooler only. Some trimming of the 90-degree coupler may be required for optimal fitment, especially with older or smaller turbo setups.
