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

When you're looking to get more out of your 2008-2014 Subaru WRX STI, especially if you've modified it or plan to, managing intake air temperature is key. This Mishimoto top-mount intercooler kit is designed to directly replace your stock unit, helping to cool the air charge before it enters your engine. You'll receive the intercooler itself, which features durable cast aluminum end tanks that are TIG-welded to a dense bar-and-plate core. Mishimoto also includes new Y-pipe gaskets, a new BPV gasket, a silicone PCV hose, and a silicone throttle-body coupler, so you have everything needed for a straightforward installation.

This intercooler has a substantial 3.75-inch thick core and a total volume of 584 cubic inches. This larger volume, combined with a dense offset fin pitch, allows for optimized heat transfer. Mishimoto's testing showed a 10-degree Fahrenheit drop in intake air temperature compared to stock, and even a small but measurable gain of 5 horsepower and 7 pound-feet of torque on a stock test vehicle. This setup is capable of supporting vehicles making up to 400 horsepower at the wheels. The installation is designed to be simple, requiring no modifications to your stock A/C line and can typically be completed in under 30 minutes.

The intercooler itself comes with a durable powder-coated finish in Stealth Black, and the included hoses are a vibrant red, giving your engine bay a distinct look. Mishimoto backs this kit with their Lifetime Warranty, offering peace of mind for years of reliable service.
