I called HPF today, I ask them what is the best plugs to use the told me the stock one gap at .28 is the best. they told me to stay away from the 6097 NGK plug because those only last for about a month. I was wondering is this is true and what do you guys think. I 'm running 6097 plug on my car now I haven't change them in 2 years
