Factory Ford open element air cleaner, also came 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.

I had the top re-plated but chose to not bead blast or paint the base or remove the breather port that was added.  My eyes are not good enough to locate a date code if their is one.  This is guaranteed to be original as I obtained three of them from the estate of a Comet collector.  Please check out my prior listings for details and price of the other two I sold.  Don Rush / West Coast Classic Cougar
