so i am new to old cars to be honest, just want to get that out of the way to defend any stupid questions that may come from me.

i recently purchased a '72 280SEL

i had some questions, the first basic maintenance. i was told to use only copper plugs? i did a little research and i noticed that some people are recommending the NGK over the Bosch OEM? are copper plugs the only ones i can truly run or should run in this?

thanks for any help
