I have been trying to find info on the function of the quarter panel vents and if they could be a source of exaust fumes? I did find a post that the small gap on 1 side of the Z emblem should be facing the rear of the car. It does appear that the emblems are different and so they do appear to be made specifcally for each side. Any info on how these vents were designed to function and if it might help to block them if they are a potential source of fumes. Thanks
