OEM 1955-57 Buick Roadmaster Special Rivera Century Super 4 barrel oil bath air cleaner. This assembly has been refinished in low-gloss black to present a period correct presentation for the Buick image cars. The cannister is clean and is garnished with a GM licensed air cleaner service decal. The lid is straight and the starburst is very nice as well. The inside is clean and allows for excellent air circulation from the cannister inlet.

The four barrel base has a 4 1/8" flange and appropriately fits early WCFB carburetors of the era. The oil bath insert has been cleaned and is ready for service, or chose to replace with a more modern K&N element if desired (not included, but will provide part number after sale). Please note that a two barrel base (3" flange) is also available if preferred - please inquire first.

This assembly is very nice and will enhance your restoration. Best of all, it is becoming a hard part to find - and it is a genuine GM part!
