I replaced the plugs in the S420 with good old Bosch Super F 8 DC4s. I would have thought nothing of it but what they replaced were MB logo Beru plugs with 3 electrodes. Are these OE plugs for an M119? Are they platinum? Maybe plugs for an M111/2/3? If I buy plugs for a 95 S420 at the dealership are these the plugs I'll get?

The plugs are marked:

R1 Beru ultra 940
14FGH-8 DTURXO made in France ||| 1.0 |||
