Yes to all those who said "Non-resistor plugs" and "Ignition system in top notch condition".

Correct plugs are available from MB, Beru, NGK.

As for other ignition components, I've now got 100% MB at no small cost. But I intend this to be my last car as I'm now 69.

Failing MB, Bosch or Beru are second best. Nothing else, in my opinion.

I have in stock a Bosch and a Beru cap. And an MB one. All new. The MB one simply looks and feels better.
