Description

The COBB Tuning Subaru Top Mount Intercooler Kit is engineered to significantly increase airflow and provide more efficient cooling for the 2015-2021 Subaru WRX. This kit includes both the Top Mount Intercooler and the COBB Charge Pipe Kit. To support the increased weight of the intercooler core, a heavy-duty replacement mounting bracket is provided for the passenger side, which includes a bushing to effectively isolate vibrations from the engine block. The kit also features reinforced black silicone couplers to optimize the flow path from the turbocharger to the throttle body. Additionally, the included COBB Thrust Tunnel, constructed from wrinkle black powder-coated aluminum, attaches to the factory hood ducting to ensure maximum airflow through the intercooler core. The COBB Charge Pipe included in this kit is made from 6061 aluminum tubing and features an integrated billet transition from 2" to 2.5" for enhanced flow, while also retaining clearance for larger aftermarket radiators. It sports a wrinkle black powder coat finish for a subtle, upgraded look. The charge pipe comes with a billet turbo adapter and 5-ply silicone, facilitating a straightforward, leak-free installation. It is compatible with both the factory bypass valve and the COBB LF BPV. This intercooler kit is 50-state legal with CARB Executive Order D-660-67.
