With or without there will be wind turbulence but I find cracking the rear windows helps when using a visor.
It's to help protect rocks and small debris from flinging up and cracking the sun roof.
Sorry but I don't buy that. At most I believe they're to manage airflow over and into the vehicle and maybe for aesthetetics as well, but no way they're for preventing a moonroof from breaking due to debris.
lol when I was mentioning drag I wasn't meaning it'll be a noticeable difference on the truck. I was answering a statement above about it managing the airflow over the vehicle.
Didn't want people to get the idea that he meant it was better for the vehicle/performance for the sake of confusion because someone somewhere will get it all confused.
Get some 99runner
I was going to get one but alot of people seem to say they actually increase noise and wind turbulence in the truck. What are your experience with them?
Hi Muti
I always like to have fresh air in the car no matter the weather. With a visor I can open the sunroof a bit in the rain. There is one that has dual flaps on it to direct the wind where you want individually for the driver and passenger. I actually ordered one, but the first came broken :wow: snapped in half by UPS. The replacement is in route. I'll let you know if it sounds any different than normal ones
I paid $90 :hiding: with a coupon
effer better be awesome.
But I did install a leaf blower under the hood routed to the intake give me an added 9hp till about 2300rpm and then becomes a restriction.. Still trying to figure out a way to get it to not cause so much restriction in the intake after it passes a certian RPM.. Guess I could rig up a hobs switch
