Arlen Ness Black Method Clear Series Air Cleaner Filter 88-19 Harley Sportster

• Forged billet aluminum air cleaner featuring a polycarbonate window to view the internal working of the air intake system
• Each hidden breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes. This eliminates the need for any external hoses or hardware for a virtually closed loop system
• Polycarbonate is hard-coated for long lasting durability and protection from engine oil and UV sunlight
• Radius air inlet provides unobstructed airflow into engine
• Includes backing plate, forged filter housing, clear polycarbonate top, filter, gaskets and necessary hardware
• High-performance filter is constructed from black pre-oiled cotton for optimum flow and filtration

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