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:
* 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.

I was really surprised when after 120 miles, and not hitting reserve yet, I looked into the tank and had quite a bit more gas left than I thought I should have. The ride that day was no putt around town either, I have a 1200 sport and we were blasting thru the twistys. Had a few 100 mph blasts, and some mountains thrown in too. The V-Ductor truly does increase mileage, I would not have believed it if Ihad not experienced it myself. Well designed product. Get one!

Installed a deluxe tuners kit, new vacuum slide and a V Ductor on my 2006 Road King Custom. Replaced a Dynojet kit and drilled out slide. The difference in performance and milage was unbelievable. Averaged 45 mpg on a trip from Tucson to Fresno at 70-85 mph. At least 5mpg more than I had been getting on long open road trips. Very satisfied with quality and performance of all three products. Good info on the forums too.

I installed the cv tuners kit on my FXDX during the Winter and it greatly improved the performance of my bike. I bought the bike last December and the only upgrade the previous owner had made was to replace the exhaust with Screaming Eagle slip on mufflers. I added a K & N air filter when I rejected the carburetor. I received an email advertising the V-Ductor and since it was on sale it was a no brainer. The immediately noticeable improvement was quicker warm up on starting, smoother acceleration and deceleration and a better sounding bike. I'll be back to report any other improvements after putting some miles on the bike with this upgrade.
