coils work as described but only 1 day has passed since installation. One of the tensioning ribs on the 2 coil packages was broken. One was broken before installation that I didn't install. As one rib is broken before installation and another rib on another coil pack actually breaks during installation but leaves it in place where it was installed. When the connecting rods are broken. You can't install in the right position. The coil pack rotates more than the position it should be in, preventing the pack from fitting properly in the spark plug hole. If you buy these packs be aware that the ribs are not of very good quality, they are plastic and will likely break before or during installation. If you are not careful and delicate with them. I'll take a picture of the broken rib on the coil pack in the car tomorrow when I can see better. The photo shows a coil pack that was damaged prior to installation in the package.
