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.
I use NGK on my supercharged Roush. The recommended for supercharged engines is 28 to 30k miles. The only thing that you need to research with the e85 tune is whether or not you need a hot plug or a cooler plug. Roush calls for a cooler plug
Some weekend progress after work, got the plugs changed out and fresh air filters are in.
I actually had a generator that would take 4-6 pulls to start with the "Torch" brand sparkplug, but starts in 1-2 pulls with an NGK.
BP7ES is what I have in my Wgen. Cranks 1st turn over everytime now since I switched and instead of rolling over 10-15 times with the crappy Torch plug now takes 1 second.
I recently put in NGK LKAR7BIX-11S (93501) and some cheap amazon coils. A coil failed and I just replaced it all to be sure.
Put in NGK ILKAR7B11 (4912) around 186k miles. I've burned so much oil and did a piston soak at 205k~. I scrubbed the tips with a wire brush but it didn't do much. Lots of carbon. I really don't notice a difference.
I just changed out my sparks and found out the previous owners put these garbage plugs in it lol replaced with quality Iridium NGKs
