About This Product
For a clean, industrial look, this Arlen Ness Stage 1 Big Sucker kit features a smooth brushed stainless steel outer cover. The kit is built around a patent-pending backing plate designed to maximize airflow velocity, resulting in a noticeable increase in horsepower and torque for Milwaukee-Eight engines. It includes a high-flow cotton gauze filter pre-oiled with black oil and an integrated air venturi to smooth the intake path. The filter ring design hides the urethane edge for a professional finish. This kit fits 2018 to 2024 Softail models and 2017 to 2025 Touring and Trike models, excluding the latest 2024-2025 Street Glide and Road Glide models.
Manufacturer part number: 18-344.
