Spark plugs

[jtower97]

I pulled 3 spark plugs just to get a look at them and make sure everything looked good. Just bought the vehicle and it was 60k on it. Plugs look good. I had purchased new plugs just in case. Would it be ok to put new plugs in the 3 that I pulled and leave the others alone? Or- should I just put the old plugs back in?

Same brand?

It will not hurt (probably) to just put the new ones in but, then you are going to end up replacing the others later anyways. Why not just replace them all now, just for grins?

Were you going to put the old ones back in and return all of the new ones? Were they "that" expensive?

If in your shoes, I would put the old ones back in the cylinders they came out of and put the new ones on the shelf until 100k miles.

I bought them thinking if the old ones are bad, I’d replace.
But 3 looked good. Don’t see a need to go further
Id change them all in a heartbeat but that passenger side sure is tight!

Replace them all now,then you won’t have to deal with it for a while. They are not that hard to replace,looks worse then they really are.

Do them all at once, now or later. Keep in mind that pulling off the wires multiple times will probably result in broken plug wires.
