Are the ignition coils in this kit exactly as pictured, with the 2 indentations in the center of metal shield slightly on one side of (instead of directly inline below) the white tab near the top? My rear cylinders are quite hard to get to and 2 rear coil ports are quite narrow, thus I want to replace 6 coils (with exact shape and configuration of metal heat shield) like the genuine BMW ones I took out to ensure easy installation. Big supporter of FCP OE parts and look for easy installation.
