ARLEN NESS Inverted Series Air Filter (ref. 18-927) — Forged look, designed for the road and vintage style. This "Inverted Series" kit combines a CNC machined forged aluminium backplate and open covers with an inverted top serving as a velocity stack to better profile the air intake. The Big Sucker™ breather is concealed to maintain a clean line while connecting directly to the throttle body/carb, forming a nearly closed system without external hoses.
Designed for style-conscious riders who value quality, this filter provides optimised airflow and a refined finish for customs and touring bikes. Simple maintenance: disassemble, clean, and reassemble the synthetic filter element. Suitable for the listed Harley-Davidson models (FXSE, FXDLS, FLSTFBS 2017 1800 cc), and any Vintage/Classic or Touring configuration seeking a forged aesthetic and high-performance filtration.
