These oversized oval air cleaner assemblies dwarf the competition with their size - measuring at 17" long x 9" wide - which will make your engine bay stand out in a crowd of stale old oval air cleaners. The included stamped steel baseplate is designed to fit single 4-barrel carburetors with a standard 5-1/8" diameter neck, and the 1/2" raise is enough to clear throttle linkages, carburetor bowls, and distributors without any worry of interference. These oval air cleaners are available in 5 unique finish options to perfectly match most Holley Vintage Series valve covers, and paired together, their styling creates an unsurpassed vintage vibe.
