Big Sucker Stage I Air Filter by ARLEN NESS (Manufacturer's ref: 18-447) — an intake element designed for roadsters that want a clean look and optimized breathing without a hose factory. Its round Stage I design and black finish give a sleek and muscular style to Sportsters and other small twins.

• Concealed breather: the monoblock aluminium support plate integrates concealed breather technology with O-rings at the cylinder heads and injector/carburettor outlet, eliminating the need for additional hoses or mounting accessories.
• Filtering element: pre-oiled red filter, washable and reusable, made of four layers of surgical-grade cotton for a good balance between filtration and airflow.
• Shape and material: round black aluminium filter, rounded intake designed to limit clogging points and promote a more consistent airflow.
• Complete kit: all mounting hardware and installation instructions are included. Note: only accepts the original air filter cover.

Designed for easy integration on Harley-Davidson Sportster machines (e.g. Forty-Eight, Iron) from the listed range, this Big Sucker Stage I provides a neat finish and optimized engine breathing while remaining easy to install for the demanding DIY enthusiast.
