Looking for a way to reduce high intake temperatures on your stock or modified WRX? The solution is the Mishimoto Top-Mount Intercooler and Charge Pipe System engineered specifically for the 2015+ Subaru WRX. The stock top-mount intercooler is prone to heat soak during repeated wide open throttle pulls and during track use. 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 Top-Mount Intercooler has a 4" thick core and a total volume of 625 in3, making it one of the largest topmount intercoolers you can buy. 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 500 whp. The Mishimoto Top-Mount Intercooler endured rigorous testing, showing a 35 F temperature drop as well as a +15 whp and +8 wtq bolt-on power increase for our test vehicle equipped with a Mishimoto downpipe and Stage 2 EcuTek tune. Installation is simple, requires no modification to any parts in the engine bay, and can be completed in under 1 hour. Included with this intercooler is Mishimoto's innovative charge pipe, utilizing a one-piece construction without the need for several couplers and clamps. An innovative, air splitter is included with the intercooler, this will help divert the maximum amount of air into your Mishimoto intercooler. The kit also includes a new charge pipe to intercooler hose, an intercooler to throttle-body hose, new bypass valve hoses, and a hot side O-ring gasket. 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, with your choice of either a polished or wrinkle black charge pipe, and it includes the Mishimoto Lifetime Warranty
