Big Sucker Stage I Air Filter — ARLEN NESS (Manufacturer's Ref: 18-442). Designed for touring and custom bikes, this Stage I kit focuses on a clean look and simplified engine breathing without any visible additional parts.

The heart of the system is a single-piece black aluminium support plate with a concealed breather: each outlet is equipped with O-rings at the cylinder heads and connects directly to the injector/carburettor inlet. The result: guaranteed ventilation without hoses or external accessories. The radius air inlet and the round shape of the filter promote a more direct airflow to the carburation, while the filter is delivered pre-oiled for quick installation.

• Compatibility: designed to be compatible with the OEM air filter cover.
• Finish: matte black, Stage I design, neat custom look.
• Material: sturdy aluminium, single-piece plate.
• Ready to install: mounting hardware and instructions included.
• Recommended use: touring/universal, suitable for the Harley customs mentioned below.

Common installation examples: Harley-Davidson FXSB Breakout (2016–2017), FLS Softail Slim (2017). The Big Sucker Stage I is aimed at riders who want a neat look and cleanly integrated ventilation without complicating the installation.
