Why upgrade

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. These kits are engineered around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
