So why is everyone saying .028" gap when ALLdata and many other threads on here state .032"-.035" is actually correct?

Your AllData information is out of date. Read the following two threads for why:

and

XtremeRevolution, with the assistance of over 100 CruzeTalk members, determined there was a problem with the spark plugs in the 2011 and 2012 Cruze. He got GM to take a second look at the spark plugs in the Cruze and their response is in the first link above. The second link is my measurements and calculations supporting GM's response.

Fair enough, I just joined a few months ago, I am not understanding then what is correct now for OEM ACDelco plugs for gap and real world life in miles?

I am not interested in playing the copper plug game, I have a 350 TBI powered 95 GMC K1500 to play that game with.

I will be gapping them back to .028" then, I currently have 73K on the car, so will need new ones in 20K or so anyways.
