Product Description

The 2015+ WRX is an amazing platform, but the factory top-mount intercooler has a glass jaw: heat soak. Once you sit in traffic or do one hard pull, the intake temps skyrocket, and the ECU pulls timing. While many people rush to buy a Front Mount Intercooler (FMIC), they often forget the downside: lag. By adding feet of piping, you lose that snappy throttle response. The COBB Tuning Top Mount Intercooler is the engineering solution that gives you the best of both worlds.

COBB didn't just make a bigger brick; COBB made a smarter one. COBB partnered with Garrett (yes, the turbo legends) to source the most efficient high-density core possible. But a core is useless if air goes around it rather than through it. That’s why COBB include the COBB Thrust Tunnel. This wrinkle-black aluminum duct seals perfectly against your factory hood scoop, forcing ambient air directly through the fins. The result? You get near-FMIC cooling performance while keeping your boost response instant.

You can't flow big air through a straw. The factory charge pipe is restrictive and prone to cracking under high boost. Our kit utilizes a 6061 Aluminum Charge Pipe with a custom billet transition (2" to 2.5"). It’s mandrel-bent to smooth out turbulence and powder-coated to look OEM+. Crucially, COBB designed the geometry to clear larger aftermarket radiators—a headache common with other pipes on the market.

This core is heavy—because it's packed with aluminum density. The stock brackets can't handle it. COBB include a bespoke passenger-side mounting bracket with a rubber bushing to isolate engine vibration, ensuring your new intercooler stays secure during hard cornering.

This is the ultimate cooling upgrade for the daily driver or weekend track warrior. It solves the FA20's heat issues, increases airflow by over 30%, and keeps your engine bay looking clean and professional. If you want big power potential without waiting 3 seconds for your turbo to spool, the COBB Top Mount is the only way to go. Keep the scoop, lose the heat.
