Mishimoto 2017+ Honda Civic Type R Secondary Race Radiator

It's no secret now that while the 2017-2021 Civic Type R is designed to attack the track, it can?t always stand up to the heat. Nothing is quite as frustrating as having to cut your track time short, or pull off to the shoulder on a canyon carve due to simmering coolant. Luckily, Mishimoto is here to give the FK8's cooling system the backup it needs with our 2017-2021 Honda Civic Type R Secondary Race Radiator kit. Employing the use of one of our smaller, but efficient, radiator designs, we mounted an additional heat exchanger behind the K20C1 with robust steel brackets, tapping in after the Civic?s heater core. Utilizing the air flow generated through the engine bay the Secondary Race Radiator generates additional cooling power for the already overworked stock radiator, keeping you on the track longer. In addition to the supplementary cooling power, the 2017-2021 Honda Civic Type R Secondary Race Radiator also increases the overall coolant capacity. The Mishimoto Lifetime Warranty is also included with the radiator kit to keep your CTR cool and you worry free.
