hey guys i have a 2000 lightning with basic bolt ons and around 14-15 psi of boost. just purchashed ngk br7s to replace the tr6s. what plug gap should i use? the truck is a daily driven L and i go the track 5 - 6 times a year.

 

I have mine gapped at 36 ... They run very well, and
I don't have much hesitation at low idle speeds. But
in the winter it is a little worse ... But not bad ...

 

This should have been a sticky: Plug gap chart Thanks Tampablack99!
