01 box, first time cleaned the radiator by removing the bumper. There was a caution stated on a thread that if the front trunk lid is not lower than the bumper, audible noise may develop.
Well my boxster starts whistling at about 79 MPH. When i took it up to 100 mph, it was LOUD!!!!
Tried reseating the bumper, but no success.
Any and all recommendation will be greatly appreciated
Thanks in advance
