Arlen Ness Black Deep Cut Monster Sucker Air Filer Kit for 88-19 Harley XL XLH

• Features Big Sucker “hidden breather” technology and more filter surface area for maximum performance
• Hidden breathers are O-ringed at the heads and exit out the mouth of the throttle body to provide efficient engine breathing, eliminating the need for any external hoses or hardware
• Filter features a built-in inverted top to pull in air not only from all sides of the filter but also from the front, which results in more performance-gaining airflow
• Filter is constructed from synthetic material that is water-resistant, which in most cases eliminates the need for a rain sock
• Filter is re-usable and do not require oil, just rinse and re-use
• Includes Arlen Ness forged billet cover

Will fit '88-'90 models also; breather system is not applicable for these model years.

Will fit models with fairing lowers.
