Velocity Stack Air Cleaner Intake Filter for Harley Sportster

Maximum Airflow Velocity Stack for Harley Sportster Evolution V-Twin

Who It’s For: Designed specifically for Harley-Davidson Sportster owners running the legendary Evolution V-Twin engine from 1991 through 2016.

The Problem: The stock "ham can" air cleaner on the Evolution V-Twin is a major bottleneck for performance. It chokes the intake at higher RPMs, and the factory breather system is notorious for venting oily mist through external hoses that eventually leak onto your engine cases and chrome.

The Solution: This Velocity Stack kit replaces that restrictive factory box with a CNC-machined Billet Aluminum faceplate. By utilizing a tapered venturi design and internal breather passages, we’ve corrected the factory design flaws of the Evolution V-Twin, allowing for a cleaner look and a more aggressive intake charge without the oily mess.

Why This is the Ultimate Upgrade

• Venturi-Effect Performance: The velocity stack shape accelerates air into the throttle body or carburetor, significantly sharpening throttle response compared to the flat OEM filter plate.
• T6061 Billet Durability: Machined from high-grade billet aluminum, this housing provides a rigid, heat-resistant mounting surface that won’t warp like plastic factory components.
• Internal Breather Design: We engineered hidden passages into the bracket to route crankcase gases directly into the intake, eliminating the need for cluttered external hoses and keeping your engine fins clean.
