Servicing Your Power Filter Element An AVO Turboworld Power filter requires regular servicing. At 10,000 mile intervals (5,000 miles for dusty/sandy or other extreme operating conditions) remove your power filter element for servicing using the following procedure. Your Powerfilter can be cleaned using K+N airfilter service solvent, or by soaking it in warm, soapy water. Do not use gasoline or other harsh cleaning solvents. Do not use compressed air to dry filter, as this will damage the cotton filtration media. Let it air dry slowly. At the same time as cleaning your power filter, carefully inspect the filter for signs of damage to the cotton weave or the filter body. Replace if required. NOTE!
