I hate to make another thread on the dreaded "spark plugs" but I thought I'd share what mine looked like after 20K to allow people gauge when there's should be done (early vs later).
Forgot to upload these back when they were changed. You can guess which are the old. I measured the gap on the old ones and were a TIGHT fit at 0.032". In reality, they are probably just a hair smaller. The new ones were a perfect fit at 0.028".
