The 90 ° filter has a built-in inverted upper part to attract air not only from all sides of the filter but also from the front, which results in higher performance that generates a greater air flow

Monster Sucker Arlen Ness 90 ° intake filters feature our patented Big Sucker concealed ventilation technology and more filter surface area than any other air filter we know on the market for maximum performance

Hidden Ness respirators have ringing on the heads and exist in the mouth of the injector and carburetor to provide efficient engine breathing, eliminating the need for external hoses or fittings

Each filter is made of synthetic material that is water resistant, which in most cases eliminates the need to use a rain sock

The filters are reusable and do not require oil, just rinse and reuse

Valid for Harley Davidson Sportsters 88-17 models

Spectacular air filter with a large air inlet
