What are the hoses under the bumper on a 996 in between the radiator air scoops? (see pic) The driver side one is a yellowish clear color and the other side is black. They join together in the middle, and mine are a little worn looking. I thought I might replace them since the bumper is off at the moment, but I just can't figure out what they are. Appreciate anyone who can identify these.

I think you are absolutley right, I just couldn't think of an accurate dscription to look them up. Thanks much!
