    Cold air intake for a 3.7L PIU

    Hello! First post on here.. So thankful for this forum and the information that I have got from it. I am just wondering if a CAI for the 3.7L turbo is worth upgrading, or is the stock one decent? i am looking for a slight performance boost and a louder turbo so i would probably go with the K&N...
