Mishimoto Subaru 02-07 WRX/04-07 STi Top-Mount Intercooler Kit - Silver/Black Hoses - Not For iRHD

Mishimoto is well-known for making well-built cooling components for performance vehicles. This top-mount intercooler kit is a unique option for your 2002-2007 Subaru WRX or 2004-2007 STI, designed to help your engine breathe easier and run cooler. Unlike the stock setup which uses a Y-pipe, this Mishimoto intercooler features a single-entry inlet and a specially designed tank that promotes maximum airflow and superior air dispersion across the high-efficiency bar-and-plate core. This means cooler intake air temperatures (AITs) and a more consistent power delivery.

The bar-and-plate core itself offers increased volume and improved heat transfer compared to stock, which is crucial for maintaining performance, especially under boost. Mishimoto has rigorously tested this intercooler on both stock and modified vehicles, finding it can support up to 350 horsepower. In their testing on a 305 hp vehicle running 20-22 psi, they saw a 14 hp increase and a 30-degree drop in AITs compared to the stock intercooler. The kit is designed as a completely bolt-on installation, requiring no modifications to your vehicle. It includes everything you need to get it installed: silicone bypass hoses, a silicone crankcase ventilation hose, a silicone throttle body hose, a bypass valve gasket, and all the necessary T-bolt clamps and hardware.

This kit comes with a silver cooler and black silicone hoses, offering a clean look under the hood. Mishimoto backs this intercooler with their Lifetime Warranty, so you can be confident in its quality and craftsmanship for years to come.
