Elite II Round Air Cleaner #4266 features a design that is influenced by the original Elite Series originally released in 1985, but with a new modern take on this classic look. They're made from heavy-gauge, die-cast aluminum and are finished off with a show quality high luster polished finish. The raised fins are accented by a contrast gloss black finish between the fins for the definitive Elite Series look. Fits all popular 5-1/8" diameter carburetors and include a black anodized knurled nut. Come with a high-quality 3" pre-oiled, washable and reusable Pro-Flo Universal filter with the exclusive Pro-Charge clean strip for easy maintenance and excellent filtration.
