Designed for maximum performance, this race inspired Screamin' Eagle Heavy Breather Extreme Air Cleaner flows 20% more air than the Original Equipment air box.

• Black finish
• At speeds over 60 mph, the air cleaner experiences a ram-air effect. All-new filter design captures air from Extreme face, on front of air cleaner. Air then travels through the race inspired elbow followed by a straight shot into throttle body 
• Designed to feed a large-displacement engine enough clean air that can support output of over 150hp. This air cleaner provides a stout increase in torque throughout the mid-range, as compared to other air cleaner designs 
• Water-resistant K&N oiled-cotton filter is washable and rechargeable using K&N Air Filter Care Service Kit
• Specifically engineered to work on the massive Screamin’ Eagle 68mm throttle body found on Stage IV products, but it will also work on the factory equipped throttle body
• Standard rain sock keeps water, dust and debris from contacting your air filter - extra insurance when riding in the elements
• All models require ECM calibration
• 49-State U.S. EPA compliant
