The K&N RU-4690 is a universal round tapered air filter with a 3-inch flange, a 5-inch bottom diameter, a 4-inch top diameter, and a 7 7/8-inch height. Its tapered shape suits a range of cone-style intake setups where a standard straight element won't fit the space. Confirm the flange matches your intake tube before ordering, since universal filters are sized by flange and clearance rather than by vehicle.
