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 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.

Looking for a way to reduce high intake temperatures on your stock or modified STI? The solution is the Mishimoto direct-fit top-mount intercooler engineered specifically for the 2008-2021 Subaru WRX STI. Mishimoto engineers spent months designing and testing this new intercooler to ensure optimum performance on both the street and track. This intercooler utilizes durable cast aluminum end tanks TIG-welded to a highly efficient, dense bar-and-plate core. The Mishimoto intercooler has a 3.75 inch thick core and a total volume of 584 in3. Thanks to this volume and a very dense offset fin pitch, we are able to optimize heat transfer and support vehicles from stock up to 400 whp. This intercooler endured rigorous testing, showing a 10 degree Fahrenheit temperature drop as well as a +5 whp and +7 wtq bolt-on power increase for our stock test vehicle. Installation is simple, requires no modification to the stock A/C line, and can be completed in under 30 minutes. Included with this intercooler are new Y-pipe gaskets, a new BPV gasket, a silicone PCV hose, and a silicone throttle-body coupler. These components negate the need to gather supplies for installation, and they ensure years of reliable service. This intercooler is available in a durable powder-coated finish of Stealth Black or Sleek Silver, and it includes the Mishimoto Lifetime Warranty.
