A18589 Big Sucker Back Plate Chrome Xl88 Up

This chrome Arlen Ness Big Sucker backing plate is a premium replacement part for Stage I air cleaner kits on 1988 to 2022 Sportster models. Known for its "Stealth" design, this plate allows you to retain your stock oval two-bolt air cleaner cover while benefiting from a massive increase in airflow. The plate features Ness’s signature built-in breather tunnels, which exit at the mouth of the carburetor or throttle body to create a clean, closed-loop system. This eliminates the need for external oil hoses and prevents the common mess associated with crankcase breathers. Finished in show-quality chrome, it provides a sleek, professional look for any Sportster performance intake setup while maintaining a factory-style outer appearance.
