Description
The Mishimoto Direct-Fit Oil Cooler Kit (MMOC-CTR-17TSL) is a purpose-built cooling upgrade engineered specifically for the K20C1-powered FK8 Honda Civic Type R. Rather than replacing the factory liquid-to-liquid oil cooler, this kit works alongside it by adding a dedicated 19-row air-to-air cooler that taps into the FK8’s aero-centric front bumper for airflow. The result is a system built to keep pace with track days, aggressive tunes, and the CTR’s known tendency to run hot.
This Mishimoto oil cooler kit is designed to reduce oil temperatures by 15°F (8°C) with minimal pressure drop, giving the Civic Type R’s factory cooling setup real backup when it matters most. Sturdy stainless steel braided lines with -AN fittings carry oil to and from the cooler, while application-specific mounting brackets keep the unit positioned for proper airflow through the front wheel well without disrupting factory ductwork. As a thermostatic kit, it uses a billet aluminum sandwich plate to help prevent overcooling during cooler ambient conditions or light driving, and it retains the stock liquid-to-liquid oil cooler unit rather than deleting it. Every Mishimoto cooling product, including this oil cooler kit, is backed by the Mishimoto Lifetime Warranty.
