K & N washable High Flow Air Filter Element Fits: > 15-20 Street XG500/750 (excl. 17-20 XG750A Street Rod)

K&N is the world-wide standard in high-end quality performance air filtering systems.
They are washable and can be used as stock replacement.
The filter elements are designed with a ribbed surface that will give you up to 5 times more filter area than a regular replacement filter, dramatically increasing airflow.
The K&N filter elements have a steel body with cotton between the screens.
K&N filters decrease service intervals, are better flame resistant and will last much longer than comparable foam or paper type filters.
