[QUOTE=Ivanerrol;2182858]Maybe a cool name but they are many times the price of a plain ordinary set of non resistive NGK BP6EFS's.

I got mine through Ebay. Paid about $14 New Zealand dollars each landed at my doorstep. Way cheaper than $27 NZD each we pay here. Platinums are even more expensive!

Any ideas on the white powdery stuff?
