I'm getting ready to drop some coin on a bunch of maintenance items for both the 470 and 460. For my 460 it's getting new plugs. While hunting for non-fake Denso SK20HR11's I stumbled upon NGK Ruthenium plugs. And having never heard of these so I thought I'd see if anyone here has any experience with these plugs? @mmaguy posted about using them but nothing else was said. The internets is light on seemingly reliable information so I turn here. I'm all for paying a higher $$ premium if they do have any legit benefit like longer lasting and or better engine ignition/response.
