[Sgtmoe]

I'm changing my plugs....I'm use 2 old school plugs....is a R44ltsm AC delco plug good 2 run in a 2002 Tahoe 5.3 motor.....

Probably ok in the 02 engine, might be actually an OE spec. plug. Probably better plugs available today but if you have them run them I guess.

Assuming engine is original. Spark plug spec is on your emissions sticker under the hood on top of radiator shroud. Cross reference online from there.

That's ok to use, it's a 2 year, 24K mile plug. Old school copper. Literature says they are gapped to .044".
