Charge Pipe Kit

The COBB Tuning Charge Pipe Kit is engineered to replace the restrictive factory plastic charge pipe on the 2015-2021 Subaru WRX, aiming to increase airflow and provide an upgraded appearance under the hood. Constructed from CNC-machined 6061 aluminum tubing with a durable wrinkle black powder coat finish, this kit offers a blend of performance and aesthetics. The charge pipe features an integrated billet transition that smoothly increases the diameter from 2 inches to 2.5 inches, promoting better flow. This design also ensures it retains clearance for larger aftermarket radiators, accommodating more robust cooling setups. The kit includes a billet turbo adapter and a 5-ply silicone coupler, facilitating a straightforward and leak-free installation. For those looking to optimize their intake tract, the COBB Charge Pipe can be combined with the Big SF Intake System and TMIC Coupler to create a more restriction-free path. This charge pipe is compatible with COBB OTS (Off-The-Shelf) Maps, offering flexibility for tuning. This product is confirmed to be 50 State Legal, holding multiple California Air Resources Board (CARB) Executive Orders (EO numbers: D-660-68, D-660-218, D-660-254, D-660-300), meaning it can be legally sold and used on emissions-controlled vehicles nationwide.
