Ac Delco 41-110 spark plug

[Southbound_35]

I have a question regarding spark plug figment for a 2009 5.3 FLEX. I picked up the AC Delco 41-110 and keep finding mixed answers regarding figment. Help.

Hmm, you didn't specify your vehicle, but based on some checking, it looks like the 41110 is an iridium plug, but the plugs for a 09 5.3 tahoe are the delco 41162. That's all I can really offer at the moment.

It's just part numbers that changed. They also changed the iridium to the platinum for the older trucks to lower cost. Your 110s are the original iridium part number. You should be good to go.

They also needed with the gap. They should be pre gapped at 0.04, as opposed to 0.06 I believe.

We'll try for @swathdiver one more time....

You're good to go Victor! Just double check the gap, should be .040". GM says to discard any not to spec as the tips are very fragile and can easily break. I learned to bend the ground wire and then tap it onto my bench back into spec.
