I had the pleasure of meeting the NGK rep in there one day and asked why so many old plugs were now replaced with a single type.
Better materials - generally if you mix air and petrol at 14:1 it goes bang with the same properties and heat no matter if its in your lawn mower or Ferrari.

Thanks.
Yes, the beauty of these modern plugs with copper core, NGK being one of the first, I recollect, they have a wider heat range so no need for such a wide range of plug grades as in the old days.
