Are you looking for a way to reduce high intake temperatures on your stock or modified 2015-2021 Subaru WRX? The solution is the Mishimoto direct-fit 2015-2021 Subaru WRX Race top-mount intercooler kit engineered specifically for your highly modified 2015-2021 Subaru WRX. The stock 2015-2021 Subaru WRX intercooler is prone to heat soak during repeated wide open throttle pulls and during track use.
Mishimoto engineers spent months designing the 2015-2021 Subaru WRX parts and testing this top-mount intercooler to ensure optimum performance on your highly modified WRX. This intercooler utilizes durable cast aluminum end tanks TIG-welded to a highly efficient, dense bar-and-plate core. The Mishimoto 2015-2021 Subaru WRX intercooler has a 4" thick core and a total volume of 625 cubic inches, making it one of the largest top-mount intercoolers you can buy.
Thanks to this volume and a very dense offset fin pitch, we are able to optimize heat transfer and support your vehicle from stock up to 500 whp. This WRX 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 2015-2021 Subaru WRX 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 top-mount intercooler is Mishimoto's innovative 2015-2021 Subaru WRX charge-pipe, utilizing a one-piece construction without the need for several couplers and clamps. An application-specific air splitter is included with the top-mount intercooler to help divert the maximum amount of air into your Mishimoto 2015-2021 Subaru WRX top-mount intercooler.
The WRX top-mount intercooler kit also includes a new charge-pipe to intercooler hose, an intercooler to throttle body hose, and a new bypass valve hoses. These 2015-2021 Subaru WRX parts negate the need to gather supplies for installation, and they ensure years of reliable service. This Subaru WRX intercooler is available in a durable powder-coated finish of Silver and Black, with your choice of either a polished, wrinkle black, or wrinkle red pipe, and, like all our Subaru WRX parts, this top-mount intercooler kit includes the Mishimoto Lifetime Warranty.

Note
This kit is rated for 300-450 whp with maximum limits of approximately 500 whp, or 35 PSI of turbo boost. Exceeding that horsepower or pressure limit may require a larger front-mount intercooler.
Tuning is not necessary after installing our top-mount intercooler and charge-pipe, but you will see optimal performance if tuning is performed after the intercooler is installed.
The top-mount intercooler will not fit with the stock engine cover due to its larger size.
