Big Sucker Air Filter by ARLEN NESS (manufacturer part no. 18-040): replacement element for the Big Sucker Stage 1 kit. Designed for US touring bikes and roadsters, this round filter maintains a custom aesthetic with its visible red cotton gauze and black outline, a signature of Arlen Ness accessories.
This filter is aimed at riders who want to restore or maintain their air intake with an original ARLEN NESS part. Its cotton gauze media is the traditional construction for Big Sucker type filters; it matches the dimensions and appearance of the kit for a direct replacement of the specified references. Careful aesthetics and contrasting finish provide an instantly recognisable custom look on a Sportster or any machine equipped with the kit.
