Mishimoto 08-14 Subaru WRX Top-Mount Intercooler Kit - Powder Coated Black & Red Hoses

If you're looking to keep intake air temperatures down on your 2008-2014 Subaru WRX, this top-mount intercooler kit from Mishimoto is a solid option. The factory intercooler can struggle with heat soak, especially when running higher boost pressures, and its plastic end tanks can even fail. Mishimoto spent time designing and testing this intercooler to perform well on both the street and the track.

This intercooler features a dense bar-and-plate core that's 3.75 inches thick, giving it a total volume of 584 cubic inches. This design, along with a specific fin pitch, helps optimize heat transfer and supports vehicles making up to 400 horsepower at the wheels. In testing on a stock vehicle, it showed a 12-degree Fahrenheit drop in intake temperatures and a modest gain of 6 horsepower and 8 pound-feet of torque right out of the box. The end tanks are made from durable cast aluminum and are TIG-welded to the core for a strong connection that can handle boost.

Installation is straightforward and doesn't require any modifications to your engine bay, typically taking less than 30 minutes. Mishimoto includes a new O-ring gasket for the turbo-to-intercooler connection and a silicone throttle-body coupler, so you have the necessary parts for a clean install. This kit comes with black powder-coated end tanks and red silicone hoses, and it's backed by Mishimoto's Lifetime Warranty.
