The Mishimoto direct-fit 2015+ Subaru WRX top-mount intercooler kit engineered specifically for the 2015+ Subaru WRX. The stock 2015+ Subaru WRX intercooler is prone to heat soak during repeated wide open throttle pulls and during track use. Mishimoto engineers spent months designing the 2015+ Subaru WRX parts and testing this new 2015+ Subaru WRX top-mount intercooler to ensure optimum performance on both the street and track. This 2015+ Subaru WRX intercooler utilizes durable cast aluminum end tanks TIG-welded to a highly efficient, dense bar-and-plate core. The Mishimoto 2015+ Subaru WRX intercooler has a 4 thick core and a total volume of 625 in3, making it one of the largest top-mount intercoolers you can buy.
