I'm not even sure you can buy the same plugs the manufacturer used on this engine ... it was three with the electrode platinum coated ... and the other three with the plug base coated. It saved a wee bit of cost ... but the plugs had to be located in the correct cylinder. It is much easier to used "double" platinum (base coated and electrode coated) plugs and use them "anywhere" avoiding confusion.
I guess it is true that double platinum plugs are not "required" ... but you will certainly get more life out of them. I think I'm on my third set ... and this set should last until 300 kmiles is reached.
