Subaru WRX STi Hard Pipe Kit - Hot Side - COBB - `16-`27. A purpose-built replacement for the factory hot-side charge pipe, this COBB kit provides a robust, high-flow path from the turbo to the intercooler.

Engineered for enthusiasts who want consistent performance, the aluminum hard pipe helps reduce expansion under boost and maintain airflow to the top-mount intercooler. Bead-rolled ends and multi-ply silicone couplers work together to keep connections secure, while quality clamps and vehicle-specific routing support reliable fitment. The result can be crisper boost response and dependable operation on daily, spirited, or track-focused builds.
