Good plugs

I replaced mine and left the stock gap (.050) This ran fine on the stock tune, when I upgraded to GMS1 it caused a misfire at higher rpm's. I regapped to the LNF stock gap (.034) which caused horrible drivability issues. I called Autolite support and they gave me the propper gap for these plugs in the LNF, which is .043-.045. Have put well over 22,000 miles on them so far with zero issues.

Good OEM replacement plug

Got these to troubleshoot P030x code on my cobalt SS/TC. Fixed the problem, the car seems to pull harder. Need to make sure the gap is set correctly first, since they come pre-set to .050 from the manufacturer, and the LNF engine should have them set at .032-.035
