It's patently ridiculous to think anything else.
And, I'd be surprised if Mercedes' solution doesn't include Bosch plugs.

Yes and NGK's work better in older models that can accept the equivalents. And Champion resistor plugs are indeed very unreliable and have high failure rates even out of the box, based on my experience.
But we aren't talking experience here its what Benz has to say in some obscure bulletin that is hearsay at the present time.
Lets have some technical reasons for resistor vs. non resistor plugs. Its going to be sticky because the types of ignition systems differ radically over the past say 5 decades. I know some ign systems fault when they see a short, and putting plugs with platinum coated tips cause faults or fault codes to come up because the pt flakes off over time (bad idea IMHO, just a way to sell more expensive plugs to fools who are eager to part with their money).
Are you seeing what is involved here, its more than just whether or not a plug may have a resistor in it or not.
