Big Sucker Air Filter Kit by ARLEN NESS: a compact and sleek Stage I to give your roadster a clear and tidy breath. This kit features a concealed breather system with O-rings at the cylinder heads and injector/carburettor outlet, eliminating the need for additional hoses. The rounded intake promotes unobstructed airflow for a more responsive engine without unverified technical claims.
- Robust construction: steel housing with a single-piece aluminium back plate.
- Synthetic filter media, round shape, black textured finish for a sleek and race-inspired look.
- Compatible with OEM air filter cover and water-resistant for daily use.
- Concealed breather system for a clean aesthetic; all mounting hardware and instructions are included.
- Installation: suitable for Sportster XL '91-'22 equipped with CV carburettor or Delphi EFI injection. (For '88-'90 models, the breather system is not applicable.)
Ideal for roadster riders who want a custom look without sacrificing installation cleanliness: black finish, rounded lines, and neat integration. Particularly suitable for the Harley-Davidson Sportster listed in the manufacturer compatibility.
