The Mishimoto racing thermostat will promote greater cooling efficiency in your stock or modified MX-5. Once the engine is fully warmed up, Mishimoto's MX-5 NB racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures. The Mishimoto racing thermostat is the perfect addition to your street or track MX-5 and is a direct replacement for the stock thermostat.
Suits all NB 1998-2004
