Curious question.

Is the Ram Air Filter element thicker than a stock air cleaner element?

I ask because with a standard element in the air cleaner I run out of threads on the center bolt before the wing nut reaches the lid.  Yes I bought the "correct" bolt and wingnut from a Mustang vendor.

Any thoughts?

Hello kcmash,

You will find that there are going to minute differences in the filter height between manufacturers. The 71-2 ram air housing used a Motorcraft FA-50 (Ford P/N C8AZ-9601-A) which is 2.80" in height. Because of the increased carburetor height as a result of the EGR plate, the 73 air filter housing was redesigned to use a shorter height air filter element. The 73 ram air filter is Motorcraft FA-41 (Ford P/N B7SZ-9601-A) which has a 2.22" height.
