This premium, washable air filter element is a direct replacement for the Louvered Air Cleaner for CV / EFI and Super E carburetors, which come with a paper element. This long-lasting air filter element can be washed and oiled repeatedly, keeping dust out of your engine and extending the life of your top end. This air filter measures 3-7/8 inch outside diameter and is 2" tall. The paper air filter element that comes with the Louvered Air Cleaner is 2-3/16" tall, though the difference in height does not effect the mounting or fitment of the replacement premium filter.
