The truck has 138k and I have no idea when the plugs were changed by the po. There doesn't seem to be any missing but judging by the condition Inc the air filter I just changed, it wouldn't surprise me if the plugs are due.

So the plugs on the right side are iridium and the left's are copper? Why? What engineer thought of that? I assume though that they are interchangeable but just have different wear rates?
