Mishimoto Subaru 08-15 WRX STi Top-Mount Intercooler Kit - Powder Coated Silver & Red Hoses

If you're looking to keep intake air temperatures down on your 2008-2015 Subaru Impreza WRX STI, this Mishimoto top-mount intercooler kit is a solid option. Mishimoto spent months developing this intercooler to perform well on both the street and the track, ensuring it can handle the demands of a modified STI. It's designed as a direct fit, meaning installation is straightforward and doesn't require any modifications to your stock A/C line.

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 optimizes heat transfer and is capable of supporting vehicles making up to 400 horsepower at the wheels. In testing, this kit showed a 10-degree Fahrenheit drop in intake air temperature and a modest, but notable, 5 horsepower and 7 pound-feet of torque increase on a stock vehicle. The end tanks are made from cast aluminum and are TIG-welded to the core for a strong, reliable connection. The hoses are finished in a vibrant red for a custom look under the hood.

Installation is designed to be completed in under 30 minutes and comes with everything you need to get the job done. Included are new Y-pipe gaskets, a BPV gasket, a silicone PCV hose, and a silicone throttle-body coupler. This kit also comes with Mishimoto's Lifetime Warranty for peace of mind.
