Mishimoto thermostats are effective in noticeably lowering engine coolant temperatures. These thermostats are built with high-quality wax and are shipped with new rubber gaskets (where applicable) for a good, leak-free seal. They are then digitally calibrated for precise operation. Mishimoto thermostats open up at a slightly lower temperature than OEM or standard thermostats once your engine is fully warmed up. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether you have a daily driver or a modified and upgraded turbo, Mishimoto thermostats will maintain optimal temperatures to efficiently cool your application.

Hybrid Racing offers low temp thermostats for a variety of applications, including many Honda© and Acura© models from 1990 and up. The advantages of using a low-temperature thermostat in high performance or race environments are evident. Opening the thermostat's valve at a lower temperature allows coolant to flow more freely during low-load sections of the racetrack. This enables the radiator to effectively regulate the engine's temperature within the optimal range during high-load sections. If a cooling system is pushed to its limits at the racetrack and overheating becomes an issue, a low-temperature thermostat can often resolve this problem. It achieves this by allowing the radiator to perform more cooling at lower engine loads, thereby preventing or delaying overheating during high-engine loads. Overall, low-temperature thermostats provide improved engine cooling, prevent temperature hunting, offer durability, and allow for customizable cooling systems. These advantages make them a valuable component, especially in high performance applications where maintaining optimal temperatures is crucial for engine performance and longevity. Order the model recommended for your vehicle.
