MISHIMOTO Honda Civic Type R Thermostatic Oil Cooler Kit 17-21

Track sessions end quickly when the FK8 Civic Type R begins to overheat, and the factory liquid‑to‑liquid oil cooler struggles to maintain stable temperatures once the K20C1 is pushed beyond normal commuting. Aggressive driving, high ambient heat, or performance tuning all expose the limitations of the OEM system. The Mishimoto Direct‑Fit Oil Cooler Kit is engineered to support the stock cooler by adding a high‑efficiency air‑to‑air unit, ensuring consistent oil‑temperature control under demanding conditions.

This system incorporates a 19‑row air‑to‑air cooler positioned to take advantage of the FK8’s aerodynamic front bumper, delivering an average 15°F reduction in oil temperature. Application‑specific brackets secure the cooler while maintaining proper airflow through the wheel‑well ducting. Oil is routed through stainless‑steel braided lines equipped with durable -AN fittings for long‑term reliability.

The kit is available in thermostatic and non‑thermostatic configurations to prevent over‑cooling in colder climates. Cooler cores are offered in silver or black finishes. As with all Mishimoto components, the Direct‑Fit Oil Cooler Kit is backed by the Mishimoto Lifetime Warranty.
