Mishimoto Subaru 02-07 WRX/04-07 STi Top-Mount Intercooler Kit

Upgrade your charge air system with the Subaru WRX/STI Top-Mount Intercooler Kit from Mishimoto, offering a distinct option for enhanced performance. Unlike the stock Y-pipe setup, this kit features a single entry inlet, optimizing airflow and promoting superior air dispersion through the core for optimal reduction in Air Intake Temperatures (AIT).

The intercooler boasts a high-efficiency bar-and-plate core, delivering increased volume and enhanced heat transfer. Designed as a completely bolt-on kit, it requires no vehicle modifications for installation. The Mishimoto intercooler kit includes silicone bypass hoses for both the WRX and STI, a silicone crankcase ventilation hose, a bypass valve gasket, a silicone throttle body hose, and all necessary T-bolt clamps and hardware.

Undergoing rigorous testing on both stock and modified vehicles, this intercooler has demonstrated significant power gains and reduced AITs. In testing on a 305 hp vehicle running 20-22 psi of boost, it yielded a 14 hp increase and a 30-degree drop in AITs compared to the stock STI intercooler. Detailed testing results can be found in the engineering report.

Thanks to its precision-engineered and tested core construction, this intercooler is capable of supporting vehicles with up to 350 hp. Available with either a Stealth Black or Sleek Silver cooler, the Mishimoto Top-Mount Intercooler Kit comes with the Mishimoto Lifetime Warranty, guaranteeing superior product quality and craftsmanship.
