If you look on the engine it self, you'll notice a lot of open holes, with no screws in them. Thats that way for two reasons. One is for diff. comp. for the SLK32, and the Second is for added Comp. for an 8cyl motor. If you look at the coil packs on the engine block towards the firewall. You'll see ther is actually an open spot for a fourth coil pack, on both sides. I thought that was kind of a smart play on mecedes's behalf. Hell you'll save a boat load of money doing it that way.
