Ac delco Plugs=ouch
So i picked up some Ac delco Iridum plugs #41-110 for my 00 Vette and decided to be safe and just check the gap on the plugs ,
They were all over from .30-.43 seriously pregapped when made ive never seen plugs far off other then when ive removed old ones from peoples cars .

I bought a set of the Iridiums a number of years ago and they were gapped perfectly. Sounds like the plugs you got were either made on a Monday or Friday.

im sure they come pre gapped. only problem is ac delcos are just in a box and dont have any protection on the electrodes(tip), many other spark plugs have a cardboard or plastic on the treads and over the electrode to protect it in shipping.
i work at a auto parts place they come in a big tote all they are all literally tossed in there from the warehouse, then coworkers "chuck" the totes around. and occasionally the plugs can always get dropped around.
always check them!

Notice: The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.
