Since I rarely have my wifes car down long enough to remove the intake tube from the airbox to the throttle body, does anyone have an intake tube they could measure the openings at the end? I'm on my second O.E. intake that has ripped up at the airbox, so I decided to make my own out of carbon fiber and silicone ends to allow for vibrations and flexing. I'd get a silicone one, but her R53 is an auto, so I have no luck finding one. When I do this and get it done, I'll certainly post a how-to if you are having similar problems.

Any way, I need the inside diameter of the both ends of the tube. Thanks.
