Product Description

The Mishimoto MMTMIC-WRX-15XSL Street Performance Top-Mount Intercooler Kit is a high-efficiency cooling upgrade developed for 2015-2021 Subaru WRX models equipped with the FA20DIT turbo engine. Its robust bar-and-plate aluminum core with fully cast end tanks provides significantly improved charge-air cooling compared to the stock intercooler, with roughly 76 % greater core volume and 81 % more external fin area - which can yield up to ~34 °F lower outlet temperatures under load. This results in more consistent power delivery and reduced heat soak during spirited driving or tuned operation.

Finished in a sleek silver powder coat, the MMTMIC-WRX-15XSL installs directly into factory mounting locations and works with the stock engine cover and charge piping without trimming. Designed for use on stock tunes up through moderate performance setups (e.g., Stage 2), this intercooler also fits select 2014-2018 Subaru Forester XT models. Backed by Mishimoto's Lifetime Warranty, it's a dependable cooling upgrade for daily driving and performance applications where lower intake temperatures and improved throttle response are desired.
