euroitalian 62 Report post Posted September 25, 2011 You should only use Platinum plugs in these cars Bosch P/N = FGR7DQP or NGK P/N = BKR6EQUP. OEM program gives no option for non Platinum type plugs. Apart from the fact they last at least 4 x as long they have much better ignitability of the fuel resulting in a more efficient burn of the fuel charge.
