How long should a plug last? Good question. I pulled mine when I did the nominally 11000 mile service. I think it was 10500 miles. If I hadn't already bought a new plug, I would have put the old one back in, and given it no further thought for another 20000 miles. It was clean, the edges were sharp, and the gap was correct. My '07 is box stock, except that I removed the cover over the idle mixture screw. I think, after I tinkered with it, it ended up just about where it was before I bothered with it. My fuel mileage is in my signature. By the way, the exhaust pipe is not discolored, as can be seen by the picture.
