Intake Manifold Gasket Kit

This kit utilizes a redesigned, one-piece aluminum casting that is machined after production to ensure perfectly flat flanges and precise fitment. It includes 5-ply silicone couplers that are fiber-reinforced to resist distortion under high boost conditions while still providing flexibility to isolate the intercooler assembly from engine vibrations. The turbo outlet coupler is intentionally oversized and may require trimming to fit various stock-location turbo setups. Quick specs include: One-Piece Aluminum Casting, Thick Flanges to prevent cracking, Machined Flanges for a perfect seal, 5-Ply High-Grade Silicone Couplers for smooth airflow, Heat Resistant Reinforcement for coupler stability, Stainless Steel High-Torque Clamps for rust-proof security, and Black Zinc Coated Hardware. All kits come with a 90-degree turbo outlet coupler, a throttle body coupler, and stainless steel clamps. **Fitment:** This Y-Pipe Kit is specifically designed for the following Subaru models when running an OEM STI or GrimmSpeed Top Mount Intercooler: 2004-2021 Subaru STI, 2002-2007 Subaru WRX, 2004-2008 Subaru Forester XT, and 2003-2006 Subaru Baja.
