Mishimoto 05-14 TRZ 450 Performance Thermostat 79C/174F
Whether you're tearing up the trails or hauling hay in the fields, you need your Honda TRX450R/TRX450ER to stay at the optimal temperature. Long periods of idling and low-speed high-load driving can cause engine temps to creep up if your TRX's cooling system isn't maintained with quality parts. Luckily, Mishimoto has you covered with this low temp thermostat for your 2005-2014 Honda TRX450R/TRX450ER. Our thermostat fits just like stock and features a lower opening temperature to help your TRX450R/TRX450ER stay cool in hot climates or under high loads. Like all our powersports products, this low temp thermostat for your 2005-2014 Honda TRX450R/TRX450ER is backed by our Mishimoto Lifetime Warranty.
