CVP V-Ductor

The V-Ductor is the velocity stack that fits under 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 behind your stock or high flow air cleaner.

Fits all Harley models using CV style carburetors, Delphi Fuel Injection, 08-13* Touring FL, and Mikuni HSR w/ airbox adapter.
Available in the following styles:

• 1989-2006 Big Twin and Sportster.
• 2000-present Delphi fuel injected (Softail, Dyna, Sportster, pre-08 Touring).
• 2008-2013* Touring models with Throttle-By-Wire.
• Mikuni HSR 42/45 when fitted with the Mikuni to Harley airbox adapter.**

Includes gaskets.

* Note that 2014+ Touring models introduced a design change to the air cleaner backing that will not work with a V-Ductor. 2014 touring models must use an aftermarket airbox assembly (Screamin' Eagle, K&N, Cobra, Arlen Ness, etc).

** V-Ductor for Mikuni HSR 42 uses same Harley CV40 bolt pattern and requires use of the Mikuni/Harley airbox adapter supplied in your Mikuni HSR kit.
