Give your CTR the cooling power it desperately needs with the Mishimoto 2017-2021 Honda Civic Type R Performance Aluminum Radiator. Honda's top-rung Civic took the hot-hatchback world by storm, but there's still one thing that's holding it back heat. The K20C1 is quite the powerhouse in the Civic, but the stock cooling system just can't keep up. Mishimoto is here with a more durable and efficient cooling solution for your FK8. For starters, we ditched the skinny core and plastic end tanks for a full aluminum, TIG-welded construction, sure to stand up to abuse on the street, track or drag strip. Our design also features a 1.57in thick core, increasing core volume by 48-percent and external fin surface area by 102-percent for maximum heat dissipation properties. Our core also incorporates strutted tubes for maximum durability. The 2017-2021 Honda Civic Type R Performance Aluminum Radiator is available in a polished finish, and includes our magnetic drain plug to collect any metallic debris in your cooling system, This radiator is covered under the Mishimoto Lifetime Warranty for a worry-free installation.
