    Hey everyone, Read a bunch of threads about the plug gap issues on older Cruzes and decided to check mine since the Car only has 600km on it. Plug gaps were consistent @ 21-22, so I gapped them to 27.5. Car seems to idle smoother at the very least. I'll see MPG in the morning on my daily...

    So after reading the issues about the plug gaps on the Cruze's being all out of whack from the factory and the result it's had on performance, (even on the 1.8's) I decided to check/change mine. My 2012 1.8 has 47K miles and I'm the second owner. I pulled the plugs and realized they are the...

    Anyone know anywhere online that I can buy the gap tool that uses rings instead of the solid metal. I've looked all around my local parts stores, but all they have are ones with a .40 and up gap. Sent from my Droid Ultra

  8. Gen1 1.4L Turbo
    My apologies if this has been asked and answered, I searched but I never seem to have much luck with those types of searches! I read in one of the searches that the 2014 calls for different plugs than the 2014, someone mentioned that it was to drop a heat range to deal with the hesitation...
  9. Gen1 1.8L
    Hello All! So spark plug gap has been something I have been following on the forum for some time and I finally got around to playing with it myself. The 1.4T guys have a thread on the subject to compile what everyone's gaps and experience are and I wanted to do the same for the 1.8L so we can...

    Quick question: After adjusting my spark plug gap approx 200 miles ago, I've notice a pretty harsh downshift going from 29-28 MPH in the automatic transmission (I'm guessing from 4th to 3rd gear, but don't know for sure). It shifts up smoothly, but the downshift at that single point is harsh...

    Is it cheaper just to buy Iridium Spark Plugs for better performance than to buy the tools to re gap them?
  13. Gen1 1.4L Turbo
    After reading all the posts on the plug gap issue I decided to re-gap my wifes 2013 1.4T auto to 0.32" from the stock 0.25" and surprisingly it did feel better and gained about 2 mpg! So I pulled the plugs out of my 2013 1.4T manual w/Tune ( wife's is without tune ) and re-gapped to 0.32". I ran...

    Just curious what others are running for spark plug gap on their tuned Cruzen. As the weather in Arizona begins to heat up I've noticed mine beginning to bog even with an SRI, Trifecta Tune and Premium gas; so I am considering regapping the plugs from .28 to a few thousands larger. Wanted to see...

    Hi all, This is some insight mainly for those from Australia, but also a recap of the spark plug gap issue of the Chevy's. I have a 2011 Cruze CD, 1.8. After reading about the spark plug gap issues everyone else was having I thought I'd check mine too. Given we have exactly the same engine...
  20. Gen1 Powertrain
    I have a 2012 Cruze 1.4L LT RS. Over time I've installed the Trifecta Tune and Injen Colad Air intake. I've been reading through nearly all the threads on the Gaps the spark plugs should be at. So far I read that gapping to .035 has givin people better throttle response, more power in the lower...
