10 years without changing the spark plugs

[exranger06]

This thread reminds me...I should probably change the plugs in my Ranger. It's 10 years old, plugs have never even been loosened/re-tightened, let alone replaced. Only has 65k miles though.

I agree and not be replacing them with any multiple electrode designs, kind of ashamed for falling for the marketing 10+ years ago.

The electrodes do not appear even slightly worn however. I am not sure if the the platinum tip has recessed at all into the ceramic insulation. In general it is tune up time with cap rotor wires and plugs, even though there are no obvious signs that it absolutely requires them now.
