Continental Style 2 BBL and 4 BBL Air Cleaners Back in the 1950's Frank Dominianni was running his Hi-Speed Power Equipment speed shop in Valley Stream, NY. He was heavily involved with sports car racing and with the American importer of Ferrari automobiles (Luigi Chinetti). He also was a major importer of the Italmeccanica blower. He tooled up for and manufactured two and four barrel air cleaners which he called Continental Type. By far the most famous car that used these air cleaners was the 1932 Ford 3-window coupe show rod of Andy Kassa from New Jersey. O'Brien Truckers has created brand new patterns and core boxes to recreate these two air cleaners and manufacture them here in the USA. In addition, we commissioned two custom made cotton gauze washable lifetime elements which we wrap with screen and wire mesh to give our customers an air cleaner that not only looks like Frank's original Continental Type air cleaner but filters to modern day standards. The 2 BBL is made to fit carbs with a 2 5/8" neck and the 4 BBL fits all modern carbs with a 5 1/8" neck. The 2 BBL is 17 1/4" wide, 4 3/4" tall from the carb neck to the top and 8" tall overall,the 4 BBL is 20" wide, 4" tall from the carb neck to the top and 5 3/4" tall overall.

For multiple carb setups, you need 4 1/2" center to center spacing for 2BBL air cleaners or 5 3/4" spacing for 4BBL setups.
