I did this like three weeks ago only i cut more of the piping and extend the tube all the way to the fog light vent which i cut out. Total cost $0.00

. Also on another note, My Friend who bought an Injen CAI for Roughly $300.00, use to put about a car on me with his intake, and when we were stock we were dead even. Now i put about 2 Cars on him because of this mod!

GREAT DIY!!!
