Description
The ARLEN NESS Slot-Track Synthetic Stage-1 Air Cleaner eliminates restrictive external breather hoses while delivering superior intake efficiency on Twin Cam engines. By routing hidden breathers directly at the cylinder heads and exiting at the carb/injector mouth, you get cleaner aesthetics, simplified installation, and genuine performance gains from unobstructed airflow. The synthetic filter design cuts maintenance to a quick rinse—no re-oiling required—so you spend more time riding and less time servicing.
