The black one is a Bosch part but not for my 94 E320. The MB parts managers said it listed that part for a multitude of 104 engines. Now that I changed the spark plug resistors and the 3 spark plugs, the engine runs fine for the last day without the CE light coming on. Now should I leave this coil in or replace it with the proper coil. Should I bother to change the other 3 sprk plugs? I got the car going into MB to replace the EGR valve on the recall at their cost. Many thanks, Arthur.

On second thought, I think I will change that coil as the 2 plugs for that coil were fouled...and change the other 3 plugs as they are so cheap. I know this area can be problematic so I'll do the right thing.
