The black plastic tubing came off a mid 80's diplomat cold air intake, and the cold air box came off a 95 trailblazer. I had to cut a hole in the inner fender, to let the air in. There is a water shield that came off the diplomat that works well to block out any direct shots of water that may splash up. Haven't ever been out in the rain though... I used plumbing sleave to connect all the pieces. Looks almost like it came that way.
