The Zionsville Autosport M54 Competition Thermostat Plate Kit is designed to give the control of proper engine operating temperature back to the owner/builder by replacing the stock electronic thermostat with a manual unit (replaces BMW part no. 11 53 7 509 227). This allows the engine to run at the proper, and much safer, operating temperature, improving engine longevity, reduces stress from high-temp. operation, reduces heat soak, and increases power!
Kit includes:
- Modified thermostat housing
- Aluminum intermediate plate
- Thermostat housing gasket
- Mechanical thermostat – 80 Deg C
- Thermostat O-ring
- Seal ring
- Stainless steel bolt (4)
- Stainless steel washer (4)
Cover on the sensor plug harness may require removal to clear the fan once installed. A trouble code will show up in your engine computer due to the absence of the electronic control, but this is only visible to a diagnostic tool, and does not show on the instrument cluster.
