Performance Water Pump And Thermostat Kit

The stock thermostat is designed to open at 97C. This leaves your engine running fairly hot, and running for quite awhile before your thermostat will begin operation. With the Mishimoto Racing thermostat, the activation temperature becomes 74C. That's 23C cooler, meaning you can rest easy knowing your engine will stay cooler to help avoid all the problems that can be associated with an engine running hot. The water pumps in these BMW models are known for failure near 80,000 miles is a very common issue often times leaving the owner stranded. This kit provides a single stop for water pump and thermostat replacement needs to save the search and get you back on the road.
