Put in part number in box on upper right side.

If you go by model / year it recommends a resistor plug & you know better than that

But isnt the correct part # BP5EFS? The F is missing.
The 190 with the 2.6 litre engine M103 uses the above.

I used this Bosch-NGK crossreference

and had BP5ES plugs infor six weeks and car runs great.

same info found at url below as go2sl pointed out.

pro mechanic here named "autozen" - 30 yrs. expereince on mb's said he's used them from the get-go.
