Just changed them from PFR6B to PFR7B. Old ones had 16000 miles, and were regapped about 1000 miles ago which fixed a hesitation. Maybe I am as susceptible to placebo as everyone else, but it does start better, idle smoother and on boost is considerably nicer overall.
Found an interesting link to diagnosing spark plugs from Ravensblade - mine were like "normal" except orange coating all over from NF - I take it this does no harm - also saw it in my exhaust when running double on a track day.
