Curious about a few things, regarding side window Deflectors. Glue in or channel attached?
Favorite after market brand?
Do they cut wind noise when windows are closed?
Do they cut wind noise when window(s) cracked open a bit?

Do you like them or not?

Thanks, brad

I have always put them on my vehicles so that I can leave the windows cracked a bit in the Texas heat without worrying about passing showers getting my interior wet. That said, they are noisy when driving, they degrade aerodynamics (important for me in my Prius where it has an effect on gas mileage at 75mph), and they cause problems at the carwash.

On my last car, I had the kind that attaches by sliding up in the top of the window channel. Never had any problems with them. On my current car, I have the stick-on kind. About every 8-9 months I have to peel them off and replace the two-sided sticky foam strip because they start getting loose. I can tell by the way they start flapping around on the highway that I'm going to lose one soon. I'll never buy the stick-on kind again.

I bought a pick up that had them fitted. They lasted a week or two before I took them off. I found them noisy. I didn’t like the look either, but they definitely were noisy. To be honest, I’d always assumed they were a smokers accessory.

What Tobin said.

The main advantage of these deflectors is that they prevent rain getting in. They also help deflect the wasps that always seem to find their way in an open window at highway speeds.

They increase noise levels but that is hardly noticable in the rattle traps I drive.

I prefer the stainless steel deflectors that push into the window track. Unfortunately, they aren't widely available. The plastic ones last anywhere from 10 years to ten months depending on the quality of plastic.

I bought a used truck a year or two ago that had them. I had the dealer remove them for me. I don't like them. A little splash of water feels good in the heat.

If they add noise, I guess they are not for me. I don't smoke, so I don't crack windows for that. I do like fresh air when temps allow. Brad

The last few modern cars I've owned...there was little noise difference with the windows down or up. It looks, to me, like modern auto aerodynamics may have made deflectors obsolete.

I thought we were going to talk about the difference between '67 and '68 Camaros.
