What is an engine breather filter?

An engine breather filter, also known as a crankcase breather filter, helps to filter the air that is vented from the engine's crankcase. This prevents oil mist and other contaminants from being released into the atmosphere or recirculating back into the intake system.

What does the 25mm inlet and 40mm filter length mean?

The 25mm inlet refers to the diameter of the opening where the filter connects to the breather hose. The 40mm filter length indicates the physical height of the filter element itself.

Can this filter be shipped to California?

No, this BMC engine breather filter is not CARB approved and cannot be shipped to California due to emissions regulations.
