I think I will try .03 and see what happens. I wonder if these cars don't like platinum and iridium. My old Saturn hated platinum plugs, and everyone on the Saturn forum reported the same.
What Was Your Spark Plug Gap?
If you changed your spark plug gap per this thread or this thread, please report what the original values were here. If you have yet to change them, please remember to report the original values.
My case with GM has been escalated to a district case manager at GM to hopefully get some exposure on this issue. My primary goal is to allow people to go to their dealerships and have their spark plug gaps checked and corrected (as there has been a 100% error rate so far), and the more people and numbers I can present them with, the better.
If your username is on the below list, I already have your numbers down. If not, please post them. I need specific values, such as ".022, .023, .025, .025." I will also need the model year of your Cruze.
We have 37 cars recorded so far. I'd like to get at least 50. My current spreadsheet is also attached.

2011 LS Auto @ .030 all around, replaced them with Autolite iridium gaped @ .035 noticed better peddle response, RPM use to drop quite a bit before shifting now it shifts smooth without the drop off, I feel much more confident to overtake as there is no more hesitation.
They don't like platinum. The OEM plugs are iridium and once properly gapped work reasonably well. There are better plugs for the car but they don't last as long, which is what eliminated them from consideration for OEM use.I think I will try .03 and see what happens.

I'm about a week from installing my 7EIX's which is the iridium version of the popular v power coppers. I'm on OEM plugs now so I can fully feel and appreciate the difference when I do swap em.
.028" is the correct gap for all gen 1 gas Cruzes.
Since it got bumped, I later swapped to the 8EIX with a new coil pack and still happy with the choice and said gap above. Low rpms in 6th gear no tune, handles just fine. Talking a level road cruising state not a low rpm wot state from car in front slowing down to turn. I'd simply go to 5th and be well enough off to speed back up to traffic flow again.I'm about a week from installing my 7EIX's which is the iridium version of the popular v power coppers.

.035 the way to go on a 14 1.4T?
No. .028".035 the way to go on a 14 1.4T?
changed my plugs today.. car has 119k miles.. plugs are stock.. two of them were .27-28, and two were .25-.26
2011 Cruze Eco gaps of .29, .30, and 2 at .31. I am not sure if these are original or not. I bought the car with about 94,000 and it now has 103,000. Hope this helps.
Thanks again for the parts and help with my vacuum/pcv problem.

While doing other engine work I checked the plugs in my 2012 eco.
All gaps were 29, my owners manual specifies 28. I think they are 2012 factory originals as I bought at 30000 miles from dealer. What brand would GM factory have installed? NKG? All in nice condition as were springs etc. Except #2 was not tightly secured and that well had a light tan coating on the well wall. I'll post a photo if color difference is visible.

From Hesitation...GONE!
-BKR8EIX-2668 (iridium plugs), ~$25, expect ~10-15k regaps on these, ~40-50k overall life.
-BKR7E-4644 (nickel/copper plugs), ~$8, expect 15-25K out of these plugs, with a regap or two required at 5-8k intervals on stock tune.

Wonder why they don't list that on the underhood label anymore.
It's probably because the amount of drivers working on their own cars is dwindling. And any info they put there can be googled pretty easily. We wrench-turners are a dying breed.Wonder why they don't list that on the underhood label anymore.
Problem with google is mixed results though.
One guy on here asked about his rear wheel alignment and I got 4 different specs from google.
Same problem when I research motorcycles I'm considering. None of them have the same horsepower ratings for any given bike. Have to find a service manual and even those are tough to find mostly.
