Spark Plugs
I was wondering what would be the best spark plug for my 1989 300ce? I have heard that the BOSCH H9DC were a good pick.

Your best bet is to stick with original plugs. I've read too many posts from people that experienced problems with platinum plugs for Benzes that don't specify platinum. The engine and ignition system was for your car was designed with these plugs. Using anything else can alter the resistance needed for proper ignition.
