The Edelbrock Elite II round air cleaner #4272. This new line of accessories 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. Our Elite II round air cleaners fit all popular 5-1/8" diameter carburetors and include a black anodized knurled nut. They 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. Our oval air cleaners are designed to fit Edelbrock single- and dual-quad applications and should clear HEI distributors and stock parts. They come with high-quality 2-1/2" washable, pre-oiled reusable filter for excellent filtration. Overall oval air cleaner dimensions are 13-5/8" x 7-3/16".
