GZP Hi-flow air filter S&S except Shorty

The filters are constructed of multiple sheets of cotton gauze wedged in between two sheets of aluminum wire mesh. The filters are oiled to boost their filtering capacity and overall performance. This results in a filter that achieves high, nearly unrestricted air flow while retaining filtration levels critical to ensure long engine life. We offer OEM replacements and two popular aftermarket filters. Zodiac's Hi-flow air filters are washable and reusable.
