The hood scoop you might be talking about is that really tiny one that was sold? Looked like the old 05-09 hood scoops that were really tiny and funny looking?
The nicer ones need to be bolted down. The side scoupes and louvers don't really get a lot of tug from the air, the hood scoop will. This is probably why they get bolted down.
Also I'd rather not have a 350$ hood scoop come free and hit my windshield and who knows who else.
