Big Sucker Air Filter – ARLEN NESS (Ref. 18-315)
The Big Sucker™ Stage 1 kit from Arlen Ness offers a compact and tidy solution to enhance the airflow of your Harley while meeting the aesthetic requirements of the Vintage/Classic and Touring categories. Machined from CNC aluminium and presented in black and chrome finish, this round mount provides a premium look between bobber and touring without compromising on manufacturing quality.
- Filter media: pre-oiled cotton filter, washable and reusable for effective filtration and optimised airflow.
- Design: one-piece support plate, cover, seals, proprietary breather tubes, and fasteners included for a clean installation.
- Ventilation system: each breather receives an O-ring at the cylinder head and passes through the plate via dedicated tubes, the design aims to redirect excess breather oil back to the engine to mitigate oil issues on M8 engines.
- Practicality: pre-oiled, washable, and reusable filter — simple maintenance for increased longevity.
- Finish: soft radius air intake for unrestricted airflow and a neat look compatible with machines such as certain Softail 1923 (e.g. Low Rider ST, Low Rider S, Breakout 117 - 2024).
This kit is aimed at riders who want a reliable, aesthetic, and easy-to-maintain setup, combining breathing performance and high-end finish for their Harley.
