ARLEN NESS Big Sucker Stage-2 - Natural - '08-'16 FL 18-511

The ARLEN NESS Big Sucker Stage-2 air intake eliminates restrictive factory breathing, delivering measurable gains in horsepower and throttle response on your '08-'16 Harley-Davidson FL. By routing breathers directly through the intake mouth, you get cleaner engine breathing without external hoses cluttering your engine bay—all with a design that's proven on the street and track.

This Stage-2 kit features a 20% larger filter element than the original Big Sucker, providing the airflow your engine demands while maintaining efficient filtration. Choose between washable red cotton filters or premium water-resistant synthetic filters, both included with installation hardware and detailed instructions.
