Description

The Mishimoto MMTS-MIA-90L is a low-temperature racing thermostat designed to promote greater cooling efficiency in your engine. It activates at a lower temperature than standard thermostats, allowing coolant to flow through the system earlier. This helps to reduce and maintain cooler engine temperatures, especially beneficial for modified or upgraded turbo applications.

The thermostat fits the 1990-1997 Mazda Miata and is designed for easy installation. Mishimoto also includes a Lifetime Warranty with this product.
