Best Spark plug for Chevrolet Cruze

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'd use the original equipment AC Delco plug. Rockauto has them for $6.31 each, with a $3 per plug rebate offered.

Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.

I set the new ngk's i put in to 0.27 and I feel a difference already lot less hesitation off the bottom end felt like it would almost hiccup before gaining any power with the stock plugs. now i lay into it and it just goes fairly smoothly

41-156 is the new plug for the LE2 engine. Our 2016.5 got them, and they are fine. 41-123s came out of it.

The new plug is AC Delco 41-156. Cannot tell any difference in my Gen 2 after replacing plugs. It ran fine before and did afterwards as well.
