I removed the Champion plug and replaced it with an NGK and on the first pull it ran.
I use NGK Iridium's in my generators. People say I'm nuts for spending the 10.00 for one, but I never have problems starting on gas or propane which is what I use with Iridium's, and plus you'll probably never have to replace it either.
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 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.
NGK all the way, 100% of the time.
I don't trust hks, too many copycat them.
Yep. Ordered some NGK iridium plugs on Amazon, 2600 miles later the car was misfiring. The gap was toast. Counterfeit for sure.
I’ve kept to stock plugs with stage 1. I tried the recommended “colder” plugs and they failed in less than 10k miles.
