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

The Mishimoto top-mount intercooler kit for your 2008-2014 Subaru Impreza WRX features a dense, 3.75-inch thick bar-and-plate core designed to significantly lower intake air temperatures. This is crucial because the stock intercooler can suffer from heat soak, especially under higher boost pressures, which can lead to reduced engine performance and potentially damage plastic end tanks over time.

Engineered with durable cast aluminum end tanks that are TIG-welded to the bar-and-plate core, this intercooler is built to handle the demands of both street driving and track use. Its substantial volume of 584 cubic inches and a dense offset fin pitch work together to optimize heat transfer, supporting vehicles from stock up to around 400 horsepower at the wheels. In testing on a stock vehicle, this intercooler showed a notable 12°F drop in intake air temperature, along with a modest but measurable increase of 6 horsepower and 8 lb-ft of torque right out of the box.

Installation is straightforward and requires no permanent modifications to your engine bay, often taking less than 30 minutes. Mishimoto includes a new turbo-to-intercooler O-ring gasket and a silicone throttle-body coupler, so you have the necessary components for a reliable installation. This kit is available with a durable powder-coated finish in Sleek Silver with red hoses, and it comes backed by the Mishimoto Lifetime Warranty.
