They are very shy. You have to remove the cover from the top of the engine, about 6 torx plus 2 allen key grub screws holding the oil filler down. These siezed on my car and I used a centre punch to drive them out. Its coil per so one at time swap them out after emoving the coils. I have a plug socket extension bar and 1/4 drive torque wrench to do mine. Its 25 NM. They are down the end of a very deep hole.
