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
