SUBARU TOP MOUNT INTERCOOLER KIT WRX 2015-2018

The COBB Top Mount Intercooler and Charge Pipe Kit is a complete cooling and airflow upgrade for the 2015–2020 Subaru WRX. Designed to deliver unmatched efficiency, durability, and ease of installation, this kit combines COBB’s largest and most advanced top mount intercooler with a precision-engineered charge pipe for a powerful improvement in performance.

At the heart of the system is the COBB Top Mount Intercooler, featuring cast aluminum end tanks and a premium Garrett core. Measuring 15.75" x 9.65" x 3.94", it is the largest top mount core available for the WRX DIT platform, providing a significant increase in airflow and cooling capacity compared to stock or competing options. Installation remains straightforward thanks to COBB’s heavy-duty passenger-side mounting bracket and vibration-isolating bushing, ensuring secure fitment and long-term reliability. Reinforced black silicone couplers and a wrinkle black powder-coated aluminum Thrust Tunnel are included to maximize airflow through the hood ducting.

Complementing the intercooler is the COBB Charge Pipe Kit, constructed from 6061 aluminum tubing with a wrinkle black powdercoat finish for strength and a clean, OEM-plus look. The integrated billet transition expands from 2 inches to 2.5 inches, optimizing airflow while maintaining clearance for larger aftermarket radiators. Installation is simple and leak-free thanks to the billet turbo adapter, 5-ply silicone connections, and compatibility with both the factory bypass valve and COBB LF BPV.

Together, the COBB Top Mount Intercooler and Charge Pipe Kit provide cooler intake temps, greater flow efficiency, and a refined appearance under the hood—all engineered to help your WRX perform at its best.
