This Double Hump HiPo Air Cleaner Assembly is an authentic unit is modeled after the extremely rare 14" air cleaners that were standard on 260 Sprint and early HiPo 289's found in 1964-1/2-1965 Mustang, 1963-1965 Ford Falcon, 1963-1964 Shelby Cobra, 1963-1965 Ford Fairlane,1963-1965 Falcon Sprint and 1965 Shelby. Unlike other HiPo air cleaner assemblies, these feature a unique "Double Hump" chrome lid rather than the more common "flat top" lid used on later model HiPo engines. The lid also has two indents to lock the wing-nut in place securely. The base of the assembly omits the breather port and is finished in a semi-gloss black like the originals. Attention was paid to the filter as well to match the original design with a yellow filter element, a round hole perforated screen and orange gasket material to complete the authentic appearance. Make your restoration or clone stand out from the crowd with this premium quality reproduction of the highly sought after "double hump" air cleaner.
