I'm going to change plugs and coils, hopefully this upcoming weekend. I'm going with MB coils, already on the way.
But, I'm trying to decide between MB OEM plugs: https://www.fcpeuro.com/products/mer...des-0001590500 and Bosch plugs: https://www.amazon.com/dp/B08YMR8KNH...v_ov_lig_dp_it
It's clear from MB's site that they don't recommend the NGK plugs so they're off the table. But what about the Bosch plugs? Does anybody have experience with using those? Bosch Part#96347. What would you do?

MB doesn't manufacture its own spark plugs, and in all likelihood uses both NGK and Bosch plugs re-branded as MB. Autohausaz has all three plugs listed with the MB OEM p/n (000 159 05 00) with MB plugs at $22/ea., NGK at $17/ea., and Bosch at $13/ea. It would be interesting to buy a set of each and compare their construction specifically with respect to indexing. I'm yet 25K miles away from a spark plug change, so perhaps some other inquiring mind will pursue this.

When you think about it, why risk something so catastrophic when you will save $100 tops, and only change plugs every 50K miles or so. The combustion chambers in modern cars has exacting specifications, not worth the danger. Do you have the M177 motor in your car, I can't tell by your signature.

Also spark plugs dissipate heat at different rates. This list of variables is over my pay grade.
