About this product
High oil temperatures can take a serious toll on the FA20 DIT engine. Protect your investment with the Mishimoto Direct-Fit Oil Cooler Kit, engineered specifically for the 2015–2021 Subaru WRX. While the WRX offers impressive performance with its turbocharged powerplant and AWD system, the factory liquid-to-liquid cooler struggles to keep up during extended spirited driving or track use. Mishimoto’s system works alongside the OEM cooler to maintain stable, controlled oil temperatures in all conditions.
This kit features a large 19-row cooler mounted in the lower grille for maximum airflow, supported by robust, application-specific brackets. The CNC-machined aluminum thermostatic sandwich plate maintains proper oil warm-up while clearing the stock oil filter. Preassembled stainless-steel braided lines with -10AN fittings ensure secure, leak-free flow to and from the cooler. With this setup, the WRX achieves an average oil-temperature drop of 20°F (11.1°C) with minimal pressure loss, helping extend engine life and improve consistency on both street and track.
