Mishimoto 2015 Subaru WRX Top-Mount Intercooler Kit - Powder Coated Black & Wrinkle Red Pipes

Mishimoto is known for making well-built cooling components for performance vehicles. For your 2015-2021 Subaru WRX, their top-mount intercooler kit is designed to tackle heat soak, especially during aggressive driving or track use. The factory intercooler can struggle to keep intake air cool when the engine is working hard, leading to less power. This Mishimoto kit directly addresses that issue with a much larger and more efficient design.

This intercooler features a 4-inch thick, dense bar-and-plate core with cast aluminum end tanks that are TIG-welded for a strong, leak-free connection. It offers a total volume of 625 cubic inches, making it one of the biggest top-mount intercoolers available. This substantial size and the dense fin pitch help optimize heat transfer, supporting vehicles from stock all the way up to 500 horsepower. In testing, this kit showed a 35-degree Fahrenheit drop in intake air temperature and a gain of 15 horsepower and 8 pound-feet of torque when paired with a downpipe and tune.

Installation is straightforward and doesn't require any permanent modifications to your engine bay, typically taking less than an hour. The kit includes Mishimoto's one-piece charge pipe, which simplifies installation by reducing the number of couplers and clamps needed. You also get an air splitter to help direct more air into the intercooler, along with all the necessary hoses and gaskets for a complete installation. This kit comes with a Mishimoto Lifetime Warranty for peace of mind.
