plugs
I finally put new plugs and wires in my Mustang. I had 8mm accel wires since the guy before my friend I bought it off of. That's a couple years back! Probably only 22K miles though. Anyway I found something interesting.... the motorcraft plugs in there all had strange gaps. The plugs in 5,6,7,8 were all at .052, probably normal wear. The plugs in 1,2,3,4 were all gapped differently ranging from .055 to .065
They all looked normal as far as wear, they just had wierd gaps. How did this happen?

my guess would be that the person who originally installed the plugs did not check the gaps before putting them in. It is not unusual to find a wide range of gaps on plugs out of the box. Use and wear could also likely account for the additional gap and discrepancy and that is what you are finding now.

I agree w/ MDM... just go back through and re-gap them, or replace them with a fresh set... being sure to gap them all the same, of course.

I put new plugs, wires, cap & rotor before I started the thread. I was just wondering why the plugs I took out might have been gapped like that, that's all.

It probably wasn't intentional.
