Overview

The Mishimoto MMTS-WRA-87L4 is a racing thermostat engineered to improve vehicle cooling efficiency.

This thermostat opens at a lower temperature, 180 F, compared to standard thermostats which typically open at 195 F. By allowing coolant to flow through the engine sooner, it helps reduce and maintain cooler engine temperatures, leading to decreased engine wear and improved reliability. It comes with a Mishimoto Lifetime Warranty and is noted for its easy installation.

The Mishimoto MMTS-WRA-87L4 is a racing thermostat designed to enhance the cooling efficiency of your vehicle's engine. This performance thermostat activates at a lower temperature of 180 F, compared to the stock 195 F. This earlier opening allows coolant to circulate through the system sooner, effectively reducing and maintaining lower engine operating temperatures. These cooler temperatures can lead to decreased engine wear and improved overall reliability. The product features an easy installation process and is backed by the Mishimoto Lifetime Warranty. It is specifically designed to fit Jeep Wrangler models with 2.5L, 4.0L, and 4.2L engines from 1987 to 2006.
