Arlen Ness 81-308 Sidekick Series Air Cleaner Kit Titanium Finish

The Arlen Ness Sidekick Series Air Cleaner is a forged billet aluminum air cleaner designed with an angled profile that delivers superior leg room while maximizing airflow performance for Harley-Davidson Milwaukee Eight engines. This premium air cleaner combines cutting-edge engineering with distinctive styling to enhance both form and function.

Key Features:

• Forged and CNC-machined billet aluminum construction with titanium anodized finish
• Angled design provides excellent leg room without sacrificing performance
• Integrated clear polycarbonate window allows you to view your intake system in action
• Patent-pending hidden breather technology—O-ringed at the heads, passes through the backing plate and exits inside the throttle body via proprietary shooter tubes
• Integrated patent-pending oil catch/reservoir prevents oil from saturating the filter and restricting airflow
• High-performance air filter features black synthetic filter media wrapped in stainless steel mesh
• Washable and water-resistant filter—no oil required, just rinse and reuse
• Complete kit includes all necessary mounting hardware

This complete air cleaner kit eliminates external breather hoses and hardware for a clean, virtually closed-loop system. The advanced oil catch system specifically addresses oil blow-by issues common with M8 engines by directing excess breather oil back into the engine before it reaches the air filter. Designed to increase horsepower, torque, and fuel mileage while providing a bold custom appearance.
