NGK spark plugs will be exclusively fitted as original equipment on petrol versions of the new Volkswagen Phaeton. NGK has engineered a new plug, the M12 iridium IZKR7B, for the six-cylinder 3.2-litre unit.

And for the 12-cylinder 6.0-litre engine VW will use NGK's double platinum PZFR6J-11 - a development of the PFR6Q plug.
