Mishimoto Subaru 02-07 WRX/04-07 STi Top-Mount Intercooler Kit - Powder Coated Black & Black Hoses

If you're looking to get more out of your 2002-2007 Subaru WRX or STI, especially if you're running increased boost or have updated tuning, upgrading your top-mount intercooler is a smart move. This Mishimoto kit replaces the stock unit with a more efficient design that helps cool the air charge before it enters your engine. Cooler, denser air means your engine can make more power and run more reliably under load.

This intercooler features a high-efficiency bar-and-plate core, which offers more volume and better heat transfer than the factory design. The cast aluminum end tanks are built for smooth airflow, and the single-entry inlet is a unique approach that helps distribute air evenly across the core. This setup is designed to reduce intake air temperatures significantly, allowing for more aggressive tuning and noticeable power gains. Mishimoto has tested this kit on both stock and modified vehicles, and it's proven capable of supporting up to 350 horsepower. The kit comes complete with everything you need for installation, including silicone hoses for the bypass, crankcase ventilation, and throttle body, along with all the necessary T-bolt clamps and hardware. It's a direct bolt-on upgrade, meaning no modifications are needed to your vehicle.

This kit is finished in a stealth black powder coat with black silicone hoses, giving your engine bay a clean, performance-oriented look. Mishimoto backs this intercooler with their Lifetime Warranty, so you can be confident in its quality and durability for years to come.
