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

When you're pushing your 2008-2014 Subaru WRX STI hard, whether on the street or the track, keeping intake air temperatures down is key to maintaining performance. This Mishimoto top-mount intercooler kit is designed to do just that, offering a direct fit replacement for your stock unit. It's built to handle the demands of both stock and modified engines, aiming to keep your turbo running efficiently.

Mishimoto engineers spent a good amount of time developing this intercooler, focusing on a dense bar-and-plate core that's 3.75 inches thick. This design, combined with cast aluminum end tanks that are TIG-welded for strength, helps optimize heat transfer. The core offers a substantial volume of 584 cubic inches, which Mishimoto states is capable of supporting vehicles up to 400 wheel horsepower. In testing on a stock vehicle, this intercooler showed a notable 10-degree Fahrenheit drop in intake air temperature and a small but measurable gain of 5 horsepower and 7 pound-feet of torque. The kit comes in a stealth black powder-coated finish with black silicone hoses, giving your engine bay a clean, performance-oriented look. Installation is straightforward, designed to fit without needing to modify the stock A/C line, and can typically be completed in under 30 minutes.

To make installation as smooth as possible, this kit includes all the necessary gaskets for the Y-pipe and bypass valve, along with a silicone PCV hose and a silicone throttle-body coupler. These included parts mean you won't have to hunt for extra supplies, ensuring a clean install and years of reliable service. Mishimoto backs this intercooler with their Lifetime Warranty, giving you confidence in its durability.
