I pulled a couple plugs out of my newly acquired E430 today to take a look at their condition. They are a bit worn F8DPER's which leads me to believe they may be original since Bosch changed over to the FR8DPP33 in the early 2000's.

The straight across replacement for the F8DPER is FR8DPP33+ or 7422. There is also a FR8DPP33X or 8100 which is also a double platinum plug.

Does anyone know the difference between the two? I can't seem to find much. I can get the 8100's quite a bit cheaper than the 7422's.
