Thanks guys for clueing me in on the plugs. I have alot to learn before I get my hands and wrenches into my 300e. That's why I'm on here.

I've always used platinum plugs in my v6 Mazda-powered Probes and they always performed very good. So naturally I thought platinum.
So looks like tomorrow I will be making a trip to AutoZone to return the platinums I bought last week. Glad I didn't install them.
Again, thanks for the info.
And I will search and research before doing anything.
