Mishimoto Thermostatic Direct-Fit Oil Cooler Kit Silver - Honda Civic Type R FK8 2017-2021

The Mishimoto Direct-Fit Oil Cooler Kit lowers fluid temperatures on the 2017-2021 Honda Civic Type R FK8, which struggles to keep its K20C1 oil cool under track use or an aggressive tune. The kit adds a 19-row air-to-air cooler that uses the FK8's front bumper aero to drop oil temperatures by roughly 15 F. Application-specific brackets retain proper airflow through the front wheel well, and stainless-steel braided lines with -AN fittings carry the oil. This thermostatic kit prevents overcooling. Backed by the Mishimoto Lifetime Warranty.
