Arlen Ness Inverted Series Air Cleaner

The Arlen Ness Inverted Series Air Cleaner is a high-performance motorcycle air intake kit. It combines Arlen Ness's Big Sucker™ hidden breather technology with an inverted filter top. The inverted top draws air in through the face of the air cleaner, and the filter also draws air from the sides. The result is better airflow and a custom look for your Harley-Davidson. Each kit is also sold as an air filter, backing plate and intake upgrade.

Key Features:

• CNC machined from forged billet aluminum for strength and a precise fit and finish
• Inverted face acts like a velocity stack, pulling more air into the top of the performance filter
• Hidden breather backing plate with a radius air inlet for smooth, unobstructed airflow
• Breathers are O-ringed at the heads and exit at the throttle body or carb, forming a virtually closed-loop system with no external hoses
• High-performance filter element built for filtering air from the face and sides
• Patented oil catch and reservoir design on select styles, which helps control oil blow-by on M8 engines
• Designed to increase horsepower, torque and mileage
• Multiple styles and finishes available to suit your build
• Made in the USA
