Screamin’ Eagle Heavy Breather Extreme Air Cleaner. Designed for maximum performance, this extra-large Screamin’ Eagle Heavy Breather Extreme Air Filter flows 42% more air than a traditional Heavy Breather filter. Air moves smoothly through the filter due to an interior bell-shape feature and then travels through a unique round to an oval transitioned tube to improve leg clearance while providing unobstructed air to the throttle body. At speeds over 60 mph, the filter captures air from the front, forcing the air through a smaller area to create a RAM air effect, while the long intake tube enhances torque beyond other Ventilator and Round High-Flow Filters for enhanced acceleration. Designed to feed a large displacement engine enough clean air that can support output of over 150hp. Water-resistant filter is washable and rechargeable. Intake tube and back plate are dressed in rich, gloss black and are made from cast aluminum. All models require ECM calibration with Screamin’ Eagle Pro Street Tuner for proper installation.
