    Thread revival!

    I got to thinking I need to change plugs again so I looked up what I replaced the OEM's with. Turns out I went with Champion single platinum 3318. I can't find how long these should last. I've put about 45,000 miles since then. I suppose I should pull one and see what they look like.
