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

If you're looking to get more out of your 2002-2007 Subaru Impreza WRX or 2004-2007 STI, this top-mount intercooler kit from Mishimoto is a solid option. It's designed to replace your stock intercooler and help keep your engine's air intake temperatures down, which is crucial for performance, especially when you're running higher boost levels. This kit uses a single entry inlet, a departure from the stock Y-pipe setup, which Mishimoto says helps improve airflow and air dispersion across the core for better cooling.

The heart of this kit is its high-efficiency bar-and-plate core. This design offers more volume than stock and does a better job of transferring heat away from the compressed air coming from your turbo. Mishimoto states that their cast aluminum end tanks are durable and engineered for smooth airflow. The kit is a complete bolt-on affair, meaning you won't need to cut or modify your vehicle's existing components. It comes with everything you need for installation, including silicone hoses for the bypass valve and crankcase ventilation, a throttle body hose, a bypass valve gasket, and all the necessary T-bolt clamps and hardware.

Mishimoto has tested this intercooler on both stock and modified vehicles. Their testing showed a notable increase in horsepower and a significant drop in air intake temperatures compared to the stock STI intercooler. This intercooler is built to support vehicles making up to 350 horsepower. It also comes with Mishimoto's Lifetime Warranty, which is a good sign of their confidence in the product's quality and craftsmanship.
