The stock NGKs are part number BUR7EQ and BUR9EQ. The 7's go in the lower (leading) holes and the 9's go in the upper (trailing) holes. The trailing are colder heat range than the leading.

Is there an advantage or disadvantage of running all hotter temp or cooler temp plugs?
Or Is the standard stagger better?
Just asking because if need be i will change mine.
