Product Description

The Mishimoto MMTMIC-WRX-15XBK Street Performance Top-Mount Intercooler Kit is a direct-fit cooling upgrade engineered specifically for the 2015-2021 Subaru WRX equipped with the FA20DIT turbocharged engine. Featuring a bar-and-plate aluminum core with cast end tanks, this intercooler provides a significant increase in core volume and heat dissipation surface area compared to the stock intercooler, helping reduce intake air temperatures by as much as ~34 °F under load and improve airflow flow by ~12 %.

Designed for use with stock tunes up through moderate performance builds (e.g., Stage 2), the MMTMIC-WRX-15XBK installs without modification and retains compatibility with the factory engine cover and charge piping. Its robust construction and performance gains make it an excellent choice for WRX owners seeking reduced heat soak, improved throttle response, and more consistent performance under boost. Backed by Mishimoto's Lifetime Warranty, it's a reliable upgrade for daily drivers and weekend enthusiasts alike.
