Hi Dave,
We often get questions about water and the hood scoop and if there are any problems with water ingestion while driving in heavy rain. During the design and testing this is something that we did focus on and wanted to make sure we addressed. What we came up with is a couple things to make sure that there was going to be no problems with water ingestion. The front of the scoop sits lower then the back and so the limited amount of water that comes in through the scoop has to travel up hill to get to the back of the scoop. There are 3 drain holes located in the front of the scoop to allow any of this water to escape also. Any of the water that does make it all the way up and to the back of the scoop will fall onto the filter which is impregnated with oil, which repels the water. The filter is installed so that it sits at an angle and will cause the water to run off and drop into the bottom of the air box, where a hole is located from the factory to allow any water to drop out.
