My 2002 C230 Coupe (Kompressor)has 70,000 miles on it - time to change the plugs. Looks nice and simple, but first the ignition coils must be removed and they are held in place by "reverse TORX" bolts - male heads that need a female socket. A TORX E10 is a very sloppy fit, E8 is too small, so it seems like I need an E9, which I can't find anywhere. Any insight or suggestions out there?

If all C230K coil packs are held down by the same reverse torx head bolts, then a 1/4" socket on an extension works fine.
