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

When you're upgrading your Subaru WRX or STI, managing the heat from the turbocharger is key to making reliable power. This Mishimoto top-mount intercooler kit is designed to replace your stock unit, offering a significant improvement in cooling efficiency. It's a complete package, giving you the intercooler itself, along with all the necessary silicone hoses for the bypass valve, crankcase ventilation, and throttle body. You'll also find a bypass valve gasket, T-bolt clamps, and all the hardware needed to get it installed. This kit is a direct bolt-on, meaning no permanent modifications are needed to your vehicle.

The heart of this kit is its high-efficiency bar-and-plate intercooler core. This design offers more volume than the stock intercooler and excels at transferring heat away from the charged air. The cast aluminum end tanks are built for smooth airflow, and the single-entry inlet design helps maximize dispersion through the core. Mishimoto has tested this intercooler extensively on both stock and modified Subarus, showing it can support up to 350 horsepower. In their testing, it resulted in a 14 horsepower increase and a 30-degree drop in air intake temperatures compared to the stock STI intercooler on a 305 horsepower vehicle running 20-22 psi of boost.

This kit comes with a silver-finished intercooler and blue silicone hoses, giving your engine bay a distinct look. Mishimoto backs this kit with their Lifetime Warranty, so you can be confident in its quality and durability for your performance build.
