Re: Best Spark Plugs Ever Used
BS, I'm using the same in my Merc. I also went from Bosch to NGK in my M3 (car) and like the NGK's much better. I know of people that tried the Denso's in their cars and they didn't perform as well, guess it depends on the car too.
I think for performance the non- precious metal plugs are better. Platinum plugs and such are better for longevity, the reason lots of cars first tune-up is 100k miles.
