Big Sucker Slot Track Air Filter — ARLEN NESS (manufacturer ref. 18-308)
The Big Sucker Slot Track kit from Arlen Ness combines a Vintage/Classic look with modern craftsmanship for touring and cruiser bikes. Its round CNC-machined aluminium body features a neat black and chrome finish and a typical Slot Track design, providing a strong presence on custom bikes and recent Softails. Designed to meet the demands of M8 engines, the integrated ventilation system eliminates oil issues by redirecting excess back to the engine via proprietary breather tubes.
Ideal for custom and touring motorcycles, the Big Sucker is suitable for builds that seek to combine aesthetics, durability, and optimized breather management. Compatible with several recent Softails (e.g., Low Rider and Breakout models equipped with the 1923 cc engine).
