    I am running a Procharger set-up and using NGK TR6's.

    I had a blown Dodge Dart and I would check the plugs twice a year or if something was not working well. This was a 340 with a carb and a paxton belt blower. With all the computers and electronics on todays vehicles I would check them at the start of driving season, if everything is ok then just have fun. The new Corvette recommends 100k on plugs and that is with 638 HP

    I have a supercharged 2002 2500HD LQ4 with a ProCharger and the book says to change them every 30,000 miles. For the past 3 sets I have used AC Delco and they have looked good when they came out and the first set it had Champion plugs that did not look very good when they came out.

    The TR6's are perfect. They should last you a long long time.

    I plan on checking them come spring time. I have about 12,000 miles on them currently. I will come back to this thread and report my findings. From what I recall from a friend, they should be good for around 25-30K miles assuming all is well.
