Hood Scoops.
Thanks guys. Think I've got it figured out now.
I'm trying to remember from the pictures what kind of scoop theirs had. All I remember was that it was really low profile against the hood. So if you were driving in hard rain, wind and inertia would probably just fill it with water sliding along the hood.
Does anybody have any more info about shaker scoops? How much they are and if they require anything special? Also, does anybody know for sure how they do in the rain? I'm likely going to go with the dual snorkel, but I do like the idea of trying something a little different, and I love the way the shakers look (air grabbers too, but they're stupid expensive. I'd be cheaper trying to build my own. And to be fair... i probably could.)
