I strongly advise you to stay away from ebay. I've seen too many people buy an intake off ebay, only to find warped pipes, and bad clamps that don't work properly. I would go with Injen. They make quality cold-air intake systems, for a descent price. The ebay deals are crap in my opinion...most of the ones that look nice and shiny begin to corrode and turn colors after a few months....
