About This Product
The Arlen Ness Big Sucker Stage 1 replacement air filter is designed to maintain the performance of one of the most popular aftermarket intake systems for Harley-Davidson motorcycles. This filter features a pre-oiled cotton gauze media housed between epoxy-coated wire mesh for structural integrity. The design allows for significantly more airflow than stock paper filters while offering the convenience of being washable and reusable. It is a critical component for riders looking to refresh their Stage 1 kit without replacing the entire assembly. This filter is sold individually and provides the necessary filtration to protect internal engine components from road debris.
Manufacturer part number: 18-040.
