BMW N54, N55 and S55 engine oil cooler thermostat bypass valve.

These BMW turbo engines have a known issue of very high running temperature with very high oil temperature. Changing original oil thermostat to our oil thermostat  diverter valve will solve this problem .

It will take oil slightly longer to warm up that is why we recommended it for hotter climate daily driven and a must for any tracked/raced N54/N55/S55.

Cheap and very efficient solution. Installation takes up to 5 minutes and can be done on the street. You can change it for summer season or when going to track and change it back when it gets colder outside. Buyer will receive installation instructions.

This bypass makes the oil temperature 10-20 deg C (20-40 deg F) lower than with stock oil thermostat.
