What it does

A carter filter, also called a crankcase breather filter, fits on the end of a breather hose. It lets the crankcase vent while filtering the air that passes through the hose.

The 12mm connection suits breather hoses and fittings of that size. Check the outlet size on your rocker cover, catch can or breather fitting before ordering.

Mount the filter where it is protected from water and road spray, and check it at each service. If it becomes oily or clogged, clean or replace it so the engine can breathe freely.

Fitment

This is a universal part. Check the Fitments tab and your breather fitting size before ordering the 12mm Breather Filter.

For larger engine breathers or intakes, see the US-Racing closed air filters, which are listed in several connection sizes.

The 12mm Breather Filter gets its other name from the word carter, the term used in parts of Europe for the crankcase, so this type of filter is often sold as a carter filter. It is a simple, low-cost part, but a blocked breather can raise crankcase pressure and push oil past seals, so it is worth keeping clean. Use a hose clip or cable tie to hold the filter on the hose so it cannot shake loose, and check it is well clear of exhaust parts.
