Description

When the pressure in the motor crankcase increases, the oil is pushed out and chooses the path of least resistance. For tuned engines, the valve covers will be one of the weakest points. By providing more ventilation to the crankcase, this problem is solved.

By installing these plugs in your valve covers, you create an outlet for crankcase ventilation. These plugs are not included in most crankcase ventilation kits and will need to be purchased separately. The engine must not receive unfiltered air; with these plugs, you can also incorporate the air filter into your crankcase ventilation system.

Equipped with a double O-ring system, which eliminates leakage through the threads.
