Morning all, I was just wondering what is the purpose of the sunroof spoiler? It's the slotted spoiler that springs up at the front of the sunroof when it's opened. I have noticed its much quieter in the truck cruising down the hiway and holding the spoiler down. So when it's up it's noisy from the wind hitting it. Is its purpose to deflect air and/or bugs over the opening? I tried with back seat passangers and they said up or down makes no difference with air coming in the opening. So what's its purpose, does it need to be there?
