ARLEN NESS Monster Sucker Air Cleaner — Black – 88-04, 06-22 Sportster

The Monster Sucker air cleaner uses hidden breather technology for a reliable intake that enhances engine performance. 💨

Hidden breathers are O-ringed at the heads and exit through the throttle body mouth to provide efficient engine breathing without external hoses or hardware.

The water-resistant filter media rinses clean for repeated use and typically does not require oil.

An inverted top pulls air from all sides for increased performance-gaining airflow, and the unit will fit 1988–1990 models with the appropriate breather arrangement.
