Mishimoto Subaru 02-07 WRX/04-07 STi - Top-Mount Intercooler Kit (Black Core & Blue Hoses)
Subaru WRX/STI Top-Mount Intercooler Kit provides a unique option for upgrading your charge air system. This kit utilizes a single entry inlet compared to the stock Y-pipe setup. This unique tank design provides maximum airflow and superior air dispersion through the core, a process that results in optimal AIT reduction. This intercooler uses a high-efficiency bar-and-plate core which provides increased volume and improved heat transfer.
The kit is completely bolt-on, requiring zero modifications to your vehicle. 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 the T-bolt clamps and hardware necessary for installation. This intercooler kit has endured rigorous testing on both stock and modified vehicles and has proven to increase power and reduce air intake temperatures.
On our 305 hp test vehicle running 20-22 psi of boost, this intercooler provided a 14 hp increase and a 30-degree drop in AITs compared to the stock STI intercooler-- for more testing details, check out the engineering report! Thanks to a precision engineered and tested core construction, this intercooler will support vehicles with up to 350 hp. This kit is available with either a Stealth Black or Sleek Silver cooler and includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
