The V-Ductor is the velocity stack that fits inside your air cleaner. By funneling air through the unique and proven venturi design, the V-Ductor reduces turbulence while increasing velocity for optimal fuel mixture. Unlike vanes, grates or screens that may deflect airflow or encourage turbulence, the V-Ductor never blocks or reduces flow. Increased air density greatly improves mileage by encouraging a more complete burn of the air/fuel mixture. Bolt-on performance that installs in minutes. The only device of it's kind CNC machined and laser cut from 6061 billet aluminum and designed to install inside your stock or high flow air cleaner. 

Fits all 1989-2006 Big Twin and Sportster models using CV style carburetors,  Delphi Fuel Injection, new Touring 50mm FI, and Mikuni HSR w/ airbox adapter. 

Specify CV carb, Delphi fuel injection, Touring, or Mikuni HSR* when ordering.
