I was going to take it to my local mechanic, but he was busy. Job went easy. Some of them squeaked coming out. Just under 90K on my 2009 Lariat. It had just developed an intermittent miss. Hope it stays away now. I did not change the COP's. I used a transmission funnel to hold the new plugs as I eased them in the hole and gave them a turn or 2. That worked very well.

 

Good job. Feels good to do it yourself.
