I just replaced the stock plug in my Champion inverter with a NGK and it runs significantly better. No more random misfires.
I threw the nasty plug away, installed the NGK plug and it now starts on the first pull and runs smoothly.
I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.
I have always had luck with the NGK iridium plugs.
Denso and NGK have fared better than Autolite in my vehicles in my experience.
I owned my cruze for 5 yrs and had no problems with the NGK iridium. I paired it with a coil pack I ripped out another cruze.
Autolite or Brisk plugs with stock gap.
I have a 05 with Edelbrock SC, 11 pounds of boost, and E85.
If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.
Out of all my years replacing spark plugs. The only times I got bad spark plugs that misfired right away is the one time I ordered a fake set thru ebay(my fault for not doing my due diligence) and a set of brand new auto lites from autozone.
I purchased some Autolite XP Iridium spark plugs earlier this month and immediately installed them. Within a mile of driving, the car started shaking violently and the check engine light came on. I immediately turned around and reinstalled the old plugs and the problems went away.
