Inverted Series Air Filter - ARLEN NESS (manufacturer part no: 18-947)
Elegant and functional, this Arlen Ness "Inverted Series" kit brings a retro-modern look and optimised breathing for customs and touring bikes. The backplate is machined from billet forged aluminium, featuring the hidden Big Sucker™ breather technology and a streamlined air inlet for a smoother airflow to the throttle body or carburettor. The forged covers, with CNC machined inverted tops, serve as velocity stacks to enhance intake.
Ideal for Vintage/Classic and Touring, this filter perfectly matches Harley Davidson Softail and Breakout type machines (e.g. FXLRST, FXLRS, FXBR 1923cc on the listed models). For riders who want a refined look and a well-thought-out intake, the Inverted Series combines high-end finish and robust design.
