Mishimoto 2015 Subaru WRX Thermostatic Oil Cooler Kit - Black

If you push your 2015-2021 Subaru WRX hard, whether on the street or the track, you know that high oil temperatures can be a real problem for the FA20 DIT engine. This Mishimoto thermostatic oil cooler kit is designed to replace the stock liquid-to-liquid cooler and keep your oil temps in check. It’s a direct-fit solution that helps protect your engine and extend its life.

This kit features a sandwich plate with a rear-mounted thermostat that activates at 185 degrees Fahrenheit (85 degrees Celsius). This means the cooler only engages when your oil actually needs it, which is great for normal driving. For serious cooling, it includes a large 19-row oil cooler mounted in the front bumper with application-specific brackets for a solid installation. The kit also comes with pre-assembled stainless steel lines with -10AN fittings and a silicone bypass hose for a clean look. Mishimoto states this setup can drop oil temperatures by about 20 degrees Fahrenheit with minimal pressure loss.

This kit is a full bolt-on solution, meaning no modifications are needed for installation. It comes with the Mishimoto Lifetime Warranty for peace of mind.
