ac delco plug gap?

[Happycampers]

I purchased a set of ac delco plugs and the parts store sais the gap is 68 thousands but but that seems a bit high. Any concrete knowledge of correct gap?

They are gapped at the factory. The gap is .060. I checked a few and they are right on. The clear sleeve that they use in the package protects the electrode from damage during shipping. You're good.

Thanks for the feed back. I went to the parts store and they said my spark plugs were. 68 and they changed the gap. I installed them and something wasn't right plus I ended up with a check engine light. But after googling gap I replace with different new plugs but now my power is fluctuating so I have to run the scanmer and see what's up. This may be unrelated.

What parts store told you .068?

O'Reilly's but Im sure he was looking at something else in the Computer. I also bent one of the plug tabs on my diverter valve/secondary air injection switching valve which is the only engine fault code I have which showed up right after I Bent the prong and tried to streighten it out but when I drive it I'm experiencing fluctuating accelerator power loss but I don't fell like it could be the aisv because that just regulates the air pump on start ups. But I'm jot sure.

Always check the spark plug gap as nobody on a forum can guarantee it's correct.

Your absolutely right!

I thought you were saying that the parts store says the spec for the gap is .068, not that they actually checked the gap. You didn't mention that until post #4.

 

[Happycampers]

That's wat they said. They said the Computer is telling them. 68 and they regappe the plugs.

The factory spec is .060

Yes when I took the plugs back I took what they had in stock, Bosch and I believe they were around. 60

Should have stuck with AC Delco Iridium. You said they CHANGED the gap to .068 because of what they saw in their computer. They were wrong. The gap was probably correct at .060

41-101 is your ac delco plug number. I have checked at least 20 ac delco plugs gaps I have purchased and they were all spot on except one, but it had a crushed box. Just off by less than .05.
I have checked at least 30 older ac delco plugs, copper, and have found them all to be at the same spec, which I assume was factory.
However, when checking the gap on an iridium do be careful not to damage the electrode.
I recommend checking but you would likely be safe not doing so. Checking is cheaper than ignition components wearing out early, is how I justify it

 

[Mad_Coachman]

This is the point I was trying to make when that Lucerne guy chimed in. A lot of manufacturers advise not to check the gap so as not to risk damage to the electrode.

I just eyed set I installed but temp plugs

 

[Mad_Coachman]

I'm sure you'll be fine.

Sorry but I've seen more NC parts that are not in spec to believe everyone in manufacturing of parts are all having a good day when making any product. But if someone wants to believe in a perfect world that's their choice, me I only trust what I check and confirm. Too many years of QC supervision in the automotive industry to think and know otherwise, so it's not a chime it's banging a big f-ing bell of hands on experience.

Good for you. Feel better now? 😉

Yes as forum ignorance needs to be addressed by the less than knowledgeable posts.
