My car was running fine. I was Just changing plugs to run a 175-200 shot. these are autolites 104's all were good untill I got the the #8 plug. The electrode was melted off the end along with some of the porclin broke off
I put in autolite 103's gaped at 40 the 104's I had gapped at 38.
All the other plugs looked new and clean.The electrodes were a little blue on them like they had gotten too hot.I guss its 104 octane when spraying for me know on.Plug pic 1 (http://photos.yahoo.com/bc/funina91ss/vwp?.dir=/&.src=ph&.dnm=%238+plug+1.jpg&.view=t&.done=http%3a//photos.yahoo.com/bc/funina91ss/lst%3f%26.dir=/%26.src=ph%26.view=t) plug pic 2 (http://photos.yahoo.com/bc/funina91ss/vwp?.dir=/&.src=ph&.dnm=%238+plug+2.jpg&.view=t&.done=http%3a//photos.yahoo.com/bc/funina91ss/lst%3f%26.dir=/%26.src=ph%26.view=t) plug pic 3 (http://photos.yahoo.com/bc/funina91ss/vwp?.dir=/&.src=ph&.dnm=%238+plug+3.jpg&.view=t&.done=http%3a//photos.yahoo.com/bc/funina91ss/lst%3f%26.dir=/%26.src=ph%26.view=t)
