Did you go with the stock plugs or one step colder?
I'd like to ask, would one want a step colder or a step hotter plug? I fiddled with a BMW 320i Engine and it liked the step hotter plug. Much better torque at the lower end. Am not sure though on the higher end on a sustained basis though.
Would putting in a hotter plug wreck the engine? I d be interested if it improves fuel economy for example.
