If you buy the higher end NGKs be sure to watch out for fakes. Even from reputable suppliers.

I was looking to replace my plugs with acdelco. My existing plug is a 41110 (12621258). Rock Auto says 41162 (19417055). Probably going with the same that is in there. Why is it never easy . Any insight or thoughts? $6.17 each at Rock Auto
Ngk at Rock Auto is part # 7397 (TR51X), that doesn't seem to match the TR61X of previous post. $5.84 each
They also have a NGK Lazor Iridium # 1465 (IZTR5B11) $6.85

If I recall correctly gm changed the spark plug gap at some point. That may be the reason for the two different delco part numbers. I would think the rock auto suggestion will work fine but maybe someone here can confirm the correct delco number.

Tr5ix is a hotter plug than the tr6ix, with the same gap. From my reading I think people prefer it over the tr6 for a stock motor. Dont know anything about the lazer iridium

Might of answered my own question regarding the ac delco plug 41110 vs 41162. Looks like the 41110 is discontinued. Sorry to hijack, walleyejack.
