I suggest buying a known high quality replacement, not being picky about the exact spec, and seeing if that makes a difference. At under $5 it's a minimal cost and effort. Based on the what this engine was likely copied from, I would pick a NGK BPR4ES or BPR5ES from a vendor that doesn't have a reputation for NGK counterfeits.
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.
