Acdelco 41-962 Double Platinum Pre-gapped?

[Lsxtrucker]

Hi group! I'm just about to do a tune up on the grey ghost, and was wondering if the Acdelco 41-962 Plugs are Pre-gapped? 

 

Thanks

Supposed to be

From what I remember the iridium's are always Pre-gapped but as you know these are the Platinums recommended plugs for these engines now. Any of you all install them straight from the box? Would hate to mess anything up if they're already at .040

Well, you could check the gap if you really want...

 

I would suggest buying them from a good, well known store or a gm dealer, as while you can get them a little cheaper on amazon/ebay, you are more likely to get a knockoff product (either just shaped/stamped with ACDelco or a rejected ACDelco part), and it can take an expert on that part to tell a real one from a fake one...

I always double check. have replaced ~75 over the years and found 2-3 that were ofd.

Don't put a gapper in a platinum or iridium plug. They aren't your Grandpa's $0.99 Chevy 350 copper plugs.  The tip can easily be damaged with a gap tool. The little cardboard cylinder keeps then gapped from the factory. Anti-sieze and put em in.

Agree with Brian all except for the anti seize. Never used it. Personally preference really. And I'm almost certain GM recommends going dry, at least the torque specs are figured without the use of anti seize. Now if I planned on leaving my plugs in for 100K miles between intervals I'd use it anyways.

I always go OEM products and they should be gapped already but double check and there a little pricey I think I paid 8$ a plug when I did my 2002 gmc 5.3 but say there 100,000 mile plugs I do mine every 50 to 60
