Arlen Ness Big Sucker Stage Air Filter Kit

The Arlen Ness Big Sucker Stage Air Filter Kit is a high-flow air cleaner (air filter) upgrade for V-twin motorcycles. It replaces the restrictive stock air box with a larger-capacity intake. The result is better airflow, improved throttle response and a more aggressive look. Arlen Ness has built custom Harley-Davidson parts for decades, and the Big Sucker line reflects that experience.

Key Features:

• High-flow design: Lets the engine draw in more air than a stock intake does
• Staged performance: The Stage options match the intake to your level of engine and exhaust modification
• Replaceable filter element: Can be serviced and maintained over time
• Custom styling: Gives the air cleaner area a distinctive, performance-oriented look
• Bolt-on installation: Designed to replace the factory air cleaner assembly

For best results, pair the intake with matching exhaust and fuel tuning. Choose the variant that matches your application from the options listed on this page.
