Downeast Johnny Posted May 17, 2012 Report Share Posted May 17, 2012 I put AC Delco in my truck and they print on the box that the plugs are pre-gapped at the factory. If you find one with the wrong gap, don't use it. Get another one with the proper gap. I've read many post on the site, here, that it is easy to damage iridium plugs by trying to "gap" them. I haven't needed to try, yet. Your post got me curious and I did a search for plug instalation instructions and found this interesting link. http://www.ngksparkplugs.com/tech_support/spark_plugs/installation/index.asp?mode=nml Hope this helps you out, some.

Blown 346 Posted May 17, 2012 Report Share Posted May 17, 2012 All the plugs I get i always to adjust the gap a bit. You just have to not use too much force to gap them. Even tho the box says pre gapped I have never came across a set that are perfect. I dont use a torque wrench, I just go tight and then another quarter turn. make sure to not pull the old plugs out while the cylinder heads are hot, you can easily pull the threads right out.

kissfans03ss Posted May 17, 2012 Report Share Posted May 17, 2012 Do you guys use anti seize or anything on plugs to prevent them from seizing to the heads? Sent from my DROID BIONIC using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

T-Bag Posted May 17, 2012 Report Share Posted May 17, 2012 They're pre-gapped, use anti-sieze Quote Link to comment Share on other sites More sharing options...

kissfans03ss Posted May 18, 2012 Report Share Posted May 18, 2012 Process of illimination , either go with or without gasket or depends on the thread size of the plug. Sent from my DROID BIONIC using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
RickRolled Posted May 18, 2012 Author Report Share Posted May 18, 2012 Ok so I got the plugs finger tight any advice on how to get the wires on easier than they were to take off? Quote Link to comment Share on other sites More sharing options...
cb2big4u Posted May 19, 2012 Report Share Posted May 19, 2012 Well you should crank the plugs snug with a socket. Just feel it out. You can tell when your going to far. Atleast I could. As for wires, just pop them on there. Only one I had trouble with was the passenger by the firewall. Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted May 20, 2012 Report Share Posted May 20, 2012 Ok so I got the plugs finger tight any advice on how to get the wires on easier than they were to take off? I gave the plugs porcelain insulator's a coating of dielectric grease. (Used a Q-tip and worked some up into the boot also). Going back on was no problem. Should make them easier to take off, next time. Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted May 20, 2012 Report Share Posted May 20, 2012 Don't know a simpler way to get this info to you, so here goes. Go to this link. About the third link down is a PDF of LQ4 spec's. I downloaded it and found the spec for new plugs to be 15 ft. LB's. It took a while to sort it out andI was in a hurry, so study it yourself and see if you find the same. http://www.google.com/search?q=GM+LQ4+spark+plug+tightening+specification&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a Good luck.
