Fits all BMW Liquid Cooled R1200GS, -GSA, -R, -RT, -RS air filter boxes This is the new Rally Raid filter, with improved filtration and increased air flow.Filter your air with a re-usable GUGLAtech air filter which meets or exceeds OEM air filter specs. The filter has a 30-40 micron fabric mesh which cleans the air without restricting flow. This is a DRY mesh media filter, meaning it doesn’t need solvents to clean it, or oils to charge it for use.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.
