About This Product
Arlen Ness Stage 1 Big Sucker air cleaner kit uses a plain backing plate that fits under your original equipment air cleaner cover. The patent-pending hidden breather system needs no external hoses and stops oil blow-by. It has a red pre-oiled high-performance filter that flows more air than stock. It fits 2017 to 2025 Touring and Trike models. It does not fit 2024 to 2025 Street Glide or Road Glide models. It is a complete bolt-on kit.
Manufacturer part number: 18-457.
