Arlen Ness 600-255 Stage Method Air Cleaner Kit - 2 Blue

The Arlen Ness 600-255 Stage 2 Method™ Air Cleaner Kit is a high-performance, show-quality air intake upgrade finished in Blue. CNC machined from forged billet aluminum, the Method™ combines aggressive styling with serious airflow gains for street riders who demand both form and function.

A clear hard-coated polycarbonate window offers a unique view into the inside of your engine's intake system, while the radius air inlet provides an unobstructed path for maximum airflow delivery. The filter itself is built from high-performance black pre-oiled cotton media with a pleated perimeter design, drawing air in from all directions for improved throttle response and increased horsepower and torque.

The Method™ features Arlen Ness's patented hidden internal breather technology. Each breather is o-ringed at the heads, routed through the backing plate, and exits inside the throttle body mouth via proprietary shooter tubes — eliminating external hoses and hardware for a clean, virtually closed-loop system. An integrated oil catch/reservoir prevents engine oil from saturating the filter, protecting airflow performance over time.
