100,000 mile Plug Change
Well, I changed the plugs and drive belt today. I was supposed to change the fuel filter also but it started raining. I didn't have any problems with the plugs as most people have posted on this site. I didn't want to mess with the fuel rails so I had to work around them, it was a pain in the axx, very tight. I did however come into something I wasn't happy with. There was soooo much dirt, debris, and what looked like sand inside all the COP's boot. You can see them even on the plugs below. How it got inside there beats me.
On the first plug I worked on, I put my plug socket in and I tried and tried but it couldn't grip onto the plug. After trying a few times, I used my flashlight and looked inside. This is what I found inside. Holy Cow.
I have no idea how this could have gotten in there other than from the factory. This is the first time I've ever change the plugs since buying the truck. NOBODY has ever worked on it where they would've had to remove the COP or the plugs.
They don't look too bad for 100,000 miles...

They don't look bad. I'm glad you got them out. I've heard that you should rig a vacuum cleaner to suck the debris out of the holes so it doesn't fall into the cylinders. I've always wondered how so much crap gets into the plug hole with the COP boot covering the opening 
. My major concern about leaving the plugs untouched for 100,000 miles is the steel plugs "bonding" to the aluminum head and taking out the thread when you try to remove it. How many years for you to reach 100,000 miles?

2 Plugs per Cylinder???
Have you guys ever heard of any engine that uses 2 spark plugs per cylinder?
Check this out. I bought my new Motorcraft plugs from the local AutoZone. When I was buying them, the girl at the counter asked how many I wanted. I figured I have a V8 so I need 8. She says "well, your car uses 2 plugs per cylinder so you'll need 16." I politely declined. Am I wrong?

Yeah...Like Bobby said, some of the Rangers had them. It was called a "dual plug" setup. My uncle has this setup in his 4 banger Ranger
