I already posted this at CICCI so I thought I would post it here also. I just finished polishing a Dual CAI that a friend and I made for my NA crossfire. It is made from stainless steel. The 2 side pipes are 2 1/2" and they go into a 3" and then into the throttlebody. It produces a nice sound and improved gas mileage. The air filters are located behind the grill, the horns have been relocated behind the bumper to allow room for the filters. I purchased the Mercedes engine cover from the Mercedes dealer and it fits with minor trimming to allow for the rad hose which you can see in the pictures. I will be getting the top if the intake plenum (center of the engine cover) polished over the winter time just to finish off the polished look. Thanks for looking.
