You have impeccable timing, what with all the discussion about these non-resistor plugs not being available. :)

My grandpa's 92 190E had been running like crap, sure enough the local "quality service" had put in Champion spark plugs that are labeled with an "R"

Whunter can you point me out to the proper spark plug for this 92 190E 2.3

I'm looking to get an extra set of plugs for my 1971 280SE (6 cyl). I currently have the Bosch W7DC plugs in her. Are these still available?

Thanks for your reply.

yes Bosch are still available but I've found NGK to be equal or superior
The exact equivalent is NGK BP6ES
