Hi I have a 2003 Infiniti g35 with the Cobb Accessport and K and N drop in filter already installed on the car. I am thinking about installing the Ztube on it to get rid of the restrictive g35 tube. Only problem is Cobb says you must keep the stock intake system on car or it could cause detonation. I really don't think changing the tube would cause that considering the 350z comes stock with it and its the same motor. If anyone is fimliar with the Cobb setup and the Ztube send me some ideas. Thanks
