Inverted Series Slot Track Air Filter – ARLEN NESS (manufacturer part no. 18-925)

Designed for roadsters and Sportsters, this Inverted Series filtration kit combines an aggressive look with technical solutions aimed at air intake. The entire unit is CNC machined from forged billet aluminium and finished in black anodised with a "Slot Track" design: open-top inverted covers serving as velocity stacks and a profiled rear plate equipped with Big Sucker™ technology for optimised air entry.

• High-performance reusable and washable filters, black synthetic element encased in stainless steel mesh.
• Inverted filters with inverted pleated tops and 360° pleated sides to capture filtered air from all angles.
• Concealed breathers with O-rings at the cylinder heads, leading to the throttle body/carburettor for a nearly closed system (no external hoses required).
• Black anodised finish, robust construction suitable for daily use and road.
• Manufactured in the USA. Installation without additional external accessories.

Compatible with many Harley-Davidson Sportster models (see installation), also suitable for '88-'90 models but the breather system is not applicable to these years. This product is aimed at riders seeking a refined aesthetic and a high-performance, durable air intake solution.
