Approx. dimensions: 2″ high x 7″ diameter. Metal top. Center 5/16 NC weld nut to attach cover. Top plate is three-hole-drilled to fit standard mounting pattern for Evo air cleaners. Economically priced but high-end quality and offering superior flow; longer service intervals; better flame resistance and will last much longer than comparable foam or paper type filters. Filter elements are constructed with 4 layers of ribbed pre-oiled cotton filtering media. This will maximize air flow but still provide adequate filtering capacity; equalling the best performance filters on the market. Very durable through the use of coated wiring mesh. Washable and ready to give years of trouble-free use. Replacement for OEM 29055-89.
