What is an engine breather filter?

An engine breather filter, also known as a crankcase breather filter, helps filter the air that vents from your engine's crankcase. This prevents dirt and debris from entering the crankcase while allowing pressure to escape.

What does the 20mm inlet and 40mm filter length mean?

The 20mm inlet specifies the diameter of the hose or fitting the filter connects to. The 40mm filter length refers to the actual size of the filtering element itself, indicating the amount of filtration surface area.

Can this filter be used in California?

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

About this part

Product Details

When you're working on cleaning up your engine bay or replacing worn-out components, a fresh engine breather filter is a small but important detail. This universal breather filter from BMC is designed to help keep contaminants out of your crankcase ventilation system. It features a 20mm inlet diameter, making it suitable for a variety of applications where a smaller connection is needed.

This filter is constructed with a focus on airflow and filtration. The 40mm filter length provides ample surface area to capture particles while allowing the crankcase vapors to vent properly. It's a well-built unit that's straightforward to install on most systems that require this size connection. Just ensure your existing breather hose fits the 20mm inlet, and you're good to go.
