1 pointIf I recall correctly the vaccume line runs to a valve that closes when the engine warms up, cutting off vaccume to the motor. No or less vaccume allows the motor to open the door allowing ambiant air to enter the air cleaner. Door is normally open and closes with vaccume.
1 pointI agonized over which wheels to buy for over a year when I realized I would have to upgrade to fit rear disks. Finally pulled the trigger. 17x8 in the front and 17x9.5 in the back with Front 17X8 245/45 4.5" BS Rear 17X9 285/40 5.5" BS No fit issues and I love the new look. Kyle
