Vetterman twist or Cessna style vents

[southtarnation]

Without getting into placement opinions, which is best overall for ease of operation, completely sealing in cold and providing the most/best fresh air in use? Which have less drag and/or noise when open or closed.

Thanks for all input.

Of the various vents I have tried, I rate the ones that Stein sells the best.

... when wide open, mine will about blow the hat off my head; when closed they have zero leakage. Excellent product worth every penny.

Don't mean to hijack this thread. what size vent are most folks using? 1 5/8?

I have the smaller stein vents and they work fine. Plenty of air. I've been told I should have gotten the larger ones but I'm completely satisfied with mine.

I had planned to use naca ducts in the front hooked to some of Stien's vents but...

Question was to do with the actual vent that goes on the skin not the part on the dash or in the cabin.

I didnt mean the eyball vents but the circular twsist to open vetterman vents that require no ducting vs the rv-10 style.

Thanks for the confirmation on the eyeball vents though!

Would love to know which is better?

Venitlators from vetterman or
Rv-10/cessna/cherokee vents.

...For the back seat.


I will use steins aluminum eyeball vents and naca vents for the front. What size eyeball vent do I need for the Bonehead Composites naca vent? The sizes arent listed on the Bonehead ste.

Thanks
