Product Details

The Mishimoto MMTS-E46-99V2 Racing Thermostat is engineered to provide optimal cooling performance for BMW M52, M54, and M56 engines. This low-temperature thermostat begins opening 48°F (27°C) earlier than the stock unit, allowing coolant to flow through the radiator sooner and maintaining lower operating temperatures during spirited driving or track use.

Key Features:

  • Opens at a lower temperature than stock for improved cooling efficiency
  • Direct-fit replacement for BMW M52, M54, and M56 engines
  • Thermostat pre-installed in OEM-style housing for easy installation
  • Includes thermostat housing gasket for complete installation
  • Backed by Mishimoto Lifetime Warranty for peace of mind

This racing thermostat is ideal for enthusiasts looking to reduce engine temperatures in performance applications, track days, or hot climate conditions. The complete assembly with pre-installed thermostat and included gasket ensures a straightforward installation process.
