Mishimoto Secondary Race Radiator 2017 Honda Civic Type R

The Mishimoto Secondary Race Radiator for the 2017 Honda Civic Type R provides dedicated supplemental cooling to reduce overheating and help preserve consistent coolant temperatures during demanding track or canyon driving.

This radiator is intended to address the known thermal limits of the 2017–2021 Civic Type R, helping prevent premature session cut‑shorts or roadside stops caused by simmering coolant.

Why this matters

Improved thermal management: Adding a secondary race radiator helps dissipate excess heat generated under sustained high load, supporting longer, more consistent track stints.

Reliability under stress: Supplemental cooling reduces the risk of coolant boilover and temperature spikes that can force unscheduled exits from a session.

Mishimoto engineering: The Mishimoto name denotes a supplier focused on motorsports-grade cooling solutions designed for repeatable on-track performance and durability.

Applications

This component targets drivers who push the factory limits of the 2017–2021 Civic Type R—track day enthusiasts and aggressive canyon drivers who require improved heat rejection to maintain performance and avoid thermal-related interruptions.
