that one acording to the chart is 2 numbers in heat range hotter, but its not too hot, and is better to have a hotter plug than a colder (from what i experiensed)

did you try plugs of the same heat range, maybe its the heat range that gave you good results, if it is (the heat range) i will look them up when i change mine and test them

i already had the NGK at the same heat range but they were not as good as the boschs...
