I'll have to find the web-site selling the part I am talking about with the twist they say the product does. I didn't mean K&N or air raid said so but that simular type of air system replacement product made the claim. Thanks for letting me know that the tornado won't work on the PT. Cruiser though won't bother with it then on that car. Put the crane wires and champion plats. on my car today. It was a pain to do the plugs being so far down. I didn't want to strip them putting them in and was very careful about that. Only had to take off the 5 8 mm screws up front and loosen the air hose. That part of the job is pretty easy on the 07'.

WHAT A DIFFERENCE IT MADE!
