Installed plugs today

Installed new plugs today. Only broke one. Had extractor tool handy. What a difference. Really smooth. Went with SP514 from American Muscle. $64 and some change. This is the latest plug for the black boot cars. Great deal.

Car had 77k but should have been changed some time ago.

You're brave in my book for going to 77k with the oem plugs. I did mine around 60k and I was paranoid. Its a good thing you were prepared with the tool! I actually timed my plug change on the same day my SnapOn man comes by, just in case. Luckily, not a single one broke!

Used a 3/8 drive small impact gun. Just hit the button and pray for the best. Quote from tech at local Ford dealer. After I was done my ole man said they recommend 60k at his Ford dealer.
