It never rains in Colorado don'cha know.....but seriously louvers woud be such that the water wouldn't be a problem coming straight down.......just going fast backwards.....ha ha .....that is why I was thinking a small scoop or a baffled cowl induction type of addition to keep everything covered. Was looking at a "shaker style from back in the '70's like on the hemi cude/challenger but it just didn't look right. Also am looking at a cowl that is just 3" and intakes against the windshield.......just don't like a lot of the looks and want to try to stay close to the stock look.
