Picture 11 of 11 from Album DIY Ram Cold Air Intake
View from the back side of the bumper (with it off the truck). This is a plastic and rubber "boot" that's used in construction for when you send a pipe out the roof. I cut down the edges and used RTV silicon to stick it on the back of the fog lamp hole.
