should i go with the platinum or the non platinum ngk plugs? some of my peeps where telling me the non platinums would be better for the rotary but i dont know. what are the pros and cons?

 

Mazda specifies the platinum plugs stock for the car. Platinum simply lasts longer - that's the only reason for the difference. The price difference has narrowed a great deal, so it's worth going ahead and running the plats. Still not sure if you really get the "bang for the buck" - if the extra cost gets you a longer time before the plug needs to be replaced over the standard coppers.

But, long story short, run the platinums.
