80 degree oil thermostat • BMW 135i 335i & other | N54 N55 S55 |

A true low temperature oil thermostat for BMW N54, N55 and S55 engines.

Why it is good:

• It is not a bypass. This means that oil warm up will be as quick as with original thermostat
  
• Our thermostat is rated at 175° Fahrenheit (80° C) and reduces the operating oil temperature 20-40° F (10-20 C)
• Does not require to remove or change oil thermostat housing - replaces original thermostat
  
• Installation is super easy and takes about 5 minutes. But do NOT do it on hot engine
  
• Can be used in cold climate as it will keep closed until the engine reaches optimal temperature
