Thanks everyone... I'm changing the plugs tomorrow morning (and probably into the afternoon and evening, with this UIM removal BS)

I'll tell you how it comes out....or what scrap yard I had it towed to.

What is the torque spec on the spark plugs? Nothing came with the box to even hint what it is.

Plugs manufacturer sites usually list the torque. Is different for the ones with conical seat from the ones with deformable washer.
Of course, Motorcraft not being the manufacturer of said plugs (or any plugs), doesn't provide that "detail".

Did the deed today. Removing the UIM wasn't as daunting a task as I thought it would be, but it's still a stupid thing to have to do to just change plugs. The old plugs weren't half bad after 90K miles. Gaps were still in spec. I already notice better gas mileage on my fuel computer with the new iridiums, though.

Now on to the rear struts. Another brilliant design called a pinch bolt. I guess they don't have any more better ideas at Ford.

Rear struts...if you live in a salt belt area...work the bolt out slowly. loosen 1 turn, tighten 1 turn, loosen 2 turns, tighten 1 turn, etc. Prevent the bolt from snapping the head off. Heavy applications of heat and PB Blaster help.

Or impact tools.

Or if you live in a non-salty area, crank 'em off!

Bob, I wouldn't reuse or replace the oem pinch bolts. Instead, grab a couple of grade#8 7/16" bolts 2.5" long and matching nyloc (plastic insert) lock nuts. Never-seize everything, lol.

I figure with 216,000 miles on my Taurus, it will be the last set of struts it will see, so I bought two new pinch bolts to replace the old ones, but I guess never say never. I never thought I'd be pulling the UIM, either.

If I go with the 7/16" bolt. will I have to drill out the hole the pinch bolt came out of so they will fit? I don't have a 1/2" drill to handle a 1/2" bit.

Salt belt...!!! When people say pass the salt here where I live in MA, we just brush it off our sleeve.
