they need to be indexed when installed or they will make contact with the cylinder heads... I was going to do mine myself but decided to let the dealer do it.. apparently the back plugs are a real *****.

I have done mine. Look in E class sections for tricks on how to do it. It's not that bad it just takes a little time and a few tools.
