This is a DRY mesh media filter, meaning it doesn’t need solvents to clean it, or oils to charge it for use, however for improved filtering we recommend treating the upper side of the filter with Rock Factory Eco Foam Air Filter Treatment.  Rock Eco Foam Air Filter Treatment

 

 

 

 

 

The mesh is reinforced by a wire screen.  This means the filter can be cleaned with compressed air and soapy water WITHOUT DAMAGE TO THE FILTER.  And that means you can use it over and over again.  Basically, this is the last air filter you’ll ever need for your bike.

Installation is quick and easy, the same process as changing an OEM paper filter.

When ordering please list your bike’s make, model, and year in the order notes.
