The front coil is a piece of cake and is just as easy as the passanger side front. However, the driver side rear is a headache. The space is tight and the problem is not getting the 12mm bolts off, which is the same as the passanger side. The rear coil pack does not have alot of slack to it interms of the wires running to it. Ontop of that, it is extremely close to the fender wall and takes some work to get out (Pic 1). The previous three coil packs you are able to take out and draw them up. However, the driverside rear you have to place below the cylinder because it is too tight to pull it up.
