2012 ECO A/T Mfg. 11/11
I don't know the plug order, but left to right... 0.020, 0.025, 0.025, 0.020 are all now gapped to 0.035.

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.

I know I did, but you're probably seeing much of the performance improvement is due to the increase in the plug gaps... the filter & resonator delete is going to hopefully improve you MPG on top of what you might see over the plug gap increase. :th_dblthumb2: I did my resonator delete about 3 weeks ago (no K&N drop in yet) & saw a 1.5MPG increase. :yahoo: I'll see what my adjusting the plugs does after this weeks tank of gas.Just regapped to. 035. Left the to right they were. 024, .025, .024, .021. I'm in a 2011 eco manual. Definitely notice an increase in low end power aswell as a smoother acceleration overall, but I also put in a KN filter and bypassed the ressonater at the same time, so I can't say how much is due to the plugs
