Big Sucker Air Filter Kit by ARLEN NESS (Manufacturer Ref: 18-324): a roadster set designed to optimise airflow and the aesthetics of your Sportster. The monoblock aluminium backplate incorporates breather technology, with concealed breathers featuring O-rings on the cylinder head side and venting inside the throttle body, creating a nearly closed system without additional hoses. Chrome finish and silver base enhance the custom look without compromising mechanical integrity.
- Pre-oiled high-performance filter: media made of 4 layers of surgical-grade cotton, washable and reusable for easy maintenance.
- Design: monoblock aluminium backplate, Radius air inlet for unobstructed flow, and mounting compatible with the OEM filter cover.
- Materials: chrome-plated steel body, premium cotton filtering media handmade in the USA.
- Complete kit: all mounting hardware and instructions included for guided installation.
This kit is intended for XL models '91-'22 equipped with CV carburettor or Delphi EFI injection. Note: for models '88-'90, the integrated breather system is not applicable. Ideal for riders seeking high-performance filtration, a neat finish, and a clean installation without additional hoses.
