Arlen Ness 81-010 Monster Sucker 90 Degree Air Cleaner Kit Black No Cover

The Arlen Ness Monster Sucker Air Cleaner Kit delivers maximum performance for your motorcycle with its innovative 90-degree forward-facing filter design. This high-flow air intake system features Arlen Ness's patented hidden breather technology that eliminates external hoses and hardware for a clean, streamlined appearance.

Key Features:

• Patented Big Sucker hidden breather technology with O-ringed heads that exit through the injector/carb mouth for efficient engine breathing
• Massive filter surface area with inverted pleated top design pulls air from the front and all sides for maximum airflow
• Synthetic filter material is water-resistant and reusable—no oil required, just rinse and reuse
• Smooth, sculpted backing plate wraps around the throttle body for excellent leg clearance
• Black powder-coated finish for a sleek, aggressive look
• Complete kit includes filter assembly and mounting hardware

This kit does not include the forged billet outer cover, which can be purchased separately and added at any time. The synthetic filter construction provides superior filtration and performance while being maintenance-friendly compared to traditional oiled filters.
