Arlen Ness 81-005 Monster Sucker 90 Degree Air Cleaner Kit Black No Cover

The Arlen Ness Monster Sucker is a high-performance 90-degree air cleaner designed for Harley-Davidson motorcycles. This kit features a massive forward-facing filter design that provides more filter surface area than any other 90-degree air cleaner on the market, maximizing airflow and engine performance.

Key Features:

• Patented Big Sucker hidden breather technology eliminates external hoses and hardware
• Hidden breathers are O-ringed at the heads and exit through the mouth of the injector or carburetor for efficient engine breathing
• Inverted pleated top pulls air from all sides of the filter as well as the front for maximum airflow
• Synthetic filter material is water-resistant, eliminating the need for rain socks in most conditions
• Smooth, sculpted backing plate wraps around the throttle body for improved leg room
• Filter is reusable and oil-free—simply rinse and reuse
• Black powdercoat finish for aggressive styling
• Forged billet covers can be added later (sold separately)

This kit does not include the Arlen Ness forged billet cover, allowing you to run an exposed filter look or add a cover at any time. CARB compliant with Executive Order D-639-8 for specific applications.
