Big Sucker Stage I Air Filter – ARLEN NESS (manufacturer part no: 18-824)
The Big Sucker Stage I from Arlen Ness features the aesthetic and meticulous finish that the brand is renowned for. Designed for roadsters, particularly the Sportster, this round monoblock aluminium filter offers a radius air intake and a concealed breather system with O-rings at the heads, which leads directly to the intake (injector/carb). The result: a clear airflow path and clean engine ventilation without the addition of external hoses.
The Big Sucker provides an immediate custom style with simple installation for those wishing to retain the original cover while smoothing the airflow to the intake. Ideal for Forty-Eight, Superlow, and other Sportster riders seeking a performance-oriented and reliable part, true to the Arlen Ness aesthetic.
