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

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

Product Description  

An intercooler upgrade is a great way to equip your flat-four with a cool charge of air! A cool, dense charge of air can allow for more aggressive tuning and increased power. The Mishimoto 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 which 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°F 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 includes a Stealth Black intercooler and black hoses and includes the Mishimoto Lifetime Warranty
