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 (K&N, Cobra, Arlen Ness, etc).

** V-Ductor for Mikuni HSR uses same Harley CV bolt pattern and requires use of the Mikuni/Harley airbox adapter supplied in HSR easy kits, not included with the V-Ductor.

  1. Seems to work

    Posted by on

    Bike seems to run smoother at speed than before. But it may have been the tuners kit I also installed.MPG seems better but still too soon to tell. Definitely the best, easiest carb rebuild I've ever done. Would recommend to any average shade tree wrench.

  2. super

    After almost a year of trying several tricks to fix my cv carb I finally listened to the people at cvp. No more hard cold start-ups. 52 mpg, and now my stock fxd will out run my friends sportster-s.

  3. Nice surprise

    Posted by on

    Last winter after head work I put the V-Ductor on my 99 Fatboy. My mileage went up by around 5 mpg. I felt it was from the proper head work I had done, and not much thought about the V-Dutor doing much towards that. At Christmas I bought one for my son in law wanting to see what it does with out head work. His 99 Fatboy got on average 4 miles per gallon less then me. After the install of the V-Dutor he was telling me of his mileage seeming better then last year. So to put it to the test we set out on a ride to compare mileage. We had a combo of 60 and 70 mph riding. Most was 60 but we got a good example of how this product is, what it says it is. He got 50.52 mpg, I got 52.01 attributing my bit better to proper head flow. And his only being 1.5 mpg behind me now, I'd say the V-Dutor is doing what it claims. I have a future son in law with a 2001 Fatboy that got 45.25 on the same ride, I can see one in his future!

  4. Expecting good results

    Posted by on

    As with the other parts I've gotten from CVP, it's a quality piece and was easy to install. The bike was recently gotten back on the road after repairs and the throttle response is excellent, time will tell what the mileage gains might be.
