Spark plugs

Has anyone used NGK*V-Power Spark Plug (BCPR6EY-11), the copper version of the BRP6ES, which is listed as nickel?

I'm running the BPR6EY in my 3.2 and am very happy. It's the V-Power version (notched v-groove center electrode) of the BPR6ES. The BPR6ES is not nickel electrode, it's copper (as is the BPR6EY). Don't know where you got the idea they're nickel. The NGK plug bodies are plated to reduce corrosion and seizing and the finish looks like nickel plating though NGK calls it "Trivalent Metal Plating".

But the plug you list (BCPR6EY-11) is a very different animal. The "C" means it uses the smaller (5/8") hex -- requires a different spark plug socket than the standard (13/16"). And the "-11" suffix means it's a wide-gap plug with a 1.1 mm (.044") gap rather than the standard approximately 0.8 mm (.032") gap.
