High Horse Performance is Veteran Owned & Operated

Your high-performance 5.7L, 6.1L, 6.4L or 6.2L HEMI needs a reliable and effective cooling system to extend engine life and perform at its absolute best. Mishimoto is proud to introduce a racing thermostat specifically designed for the 5.7L/6.1L Hemi engine. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (180°) compared to standard thermostats (203°). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether your vehicle is stock, cammed, or blown, the Mishimoto racing thermostat will provide superior cooling efficiency to keep your vehicle on the road and out of the shop. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty
*Does not Work on 6.4L Rams

    180 Degree Thermostat

    This thermostat beats out the rest. Run this in my 2019 Dodge Charger Scat Pack 392 running Diablo tune for the fans and it runs nice and cool.

    180 degree t-stat

    Posted by Dré on May 9th 2020

    Arrived next day and worked like a charm. With the old t-stat I was at 203 degrees with the 180 t-stat before tune it was at 193 steady and with tune it doesn't go past 185 degrees. Great product and highly recommended
