I do have the big 3 kit stock gapped at .032, is that OK?
As long as you're not feeling spark blowout (power drops) under load you're ok.

Okay........I'm ready to give in and admit something I have been holding back for 4 years now.
As I have said before, I have tried just about every plug considered for the Cruze and based on the past 2 weeks have to agree with obermd http://www.cruzetalk.com/forum/34-1-4l-turbo/21850-hesitation-gone-108.html that the NGK BKR7E copper plugs gapped at .028" TOGETHER with 93 Octane is simply the best setup there is! I have been a proponent for 87 octane since day one but have finally :dazed052: the light!
