ARLEN NESS - Inverted Series Air Filter (Manufacturer's Ref: 18-931)

The Arlen Ness Inverted Series Air Filter kit combines a bold roadster aesthetic with a design tailored for V-twin engines. CNC machined from billet forged aluminium and finished in black anodised, this filter features open covers with an inverted top serving as a velocity stack to optimise airflow to the throttle body/carburation. The backplate incorporates Big Sucker™ technology with a hidden breather, creating a nearly closed system without external hoses.

• Construction: CNC machined aluminium, forged covers, black anodised finish.
• Filtration: Black synthetic filter elements, wrapped in stainless steel mesh; 360° pleated sides and inverted pleated top for multidirectional airflow.
• Practicality: Reusable, washable, and water-resistant; mounts without external accessories.
• Origin: Made in the USA.

Note: also compatible with certain models from 1988–1990, but the breather system is not applicable for these model years. Ideal for roadsters and Sportsters (e.g. Harley-Davidson XL 1200 Forty-Eight and Superlow). Manufacturer's reference: 18-931.
