Spark Plug replacement

[ladorn45]

Hey

I bought a tahoe a while ago used and not sure if the owner ever did a spark plug change. SO i pulled one out and wanted to get peoples opinions on if it needs to be replaced. I bought all the plugs and spark plug wires for the tahoe but if these spark plugs look fine i might just put some antisieze on the plug and just put it back in. thoughts

Looks like they have a little carbon build up, and since you already bought plugs and wires you might as well do them it wouldn't hurt

I can still return the plugs and all but you think its worth replacing from the look of that spark plug

If it were me I would replace them. Mine looked about the same when i replaced them but im having drivability issues so im working through those. Plus it will give you peace of mind.

I would go ahead and change them cause you will have to do it someday anyway

Yup replace them. For mileage if no other reason. If they've got a 100k then don't think twice.
It's not hard and should go pretty quick. Here's a pic of what mine looked like at 124k...

Everything above. Do them but if youre gonna do it you might as well replace the 100K mile wires too. Theyre pretty cheap and you're already there.
