A quick way of increasing power and overall airflow is by replacing your Subaru WRX's stock intercooler. This COBB drop-in intercooler significantly increases airflow and helps reduce air temperatures too. Each kit is designed to fit quickly and easily with custom brackets for strength and support.

Each kit is built with cast aluminum end tanks and a high-quality Garrett core for maximum cooling ability. Each one is also reinforced with silicone couplers and includes a COBB Thrust Tunnel, which attaches to the factory under-hood ducting and seals against the face of the intercooler. This ducting ensures maximum airflow across the core. This top mount intercooler is built to maximize power and lower temps as much as possible.

Key Features:

• Improves intake air temps AND airflow!
• Direct fit design to your specific Subaru WRX.
• Bolts on to the same place as the stock intercooler. A simple drop-in install!
• Can be combined with a COBB AccessPORT tune for maximum power results.
• Lightweight air-to-air intercooler design.
• Each kit includes all the hardware and plates to install. Note that charge pipes are required to install.
• Includes a COBB Thrust Tunnel, which attaches to the factory under-hood ducting and seals against the face of the intercooler. This ducting ensures maximum airflow across the core.
