New to me 2011 Expo King Ranch 130k spark plugs

[RobE]

Purchased a new to me 2011 Expo King Ranch with 130k mi. When I test drove it, I could feel the rough idle and at wide open throttle it hesitated and the check engine light flashed momentarily. Code scanner didn't display any permanent codes, only a pending misfire on cylinder 6. I knew from experience, as this is my third 3rd gen Expedition, that in all probability the previous owner didn't change the plugs. When I pulled the old plugs, they were definitely worn and the gap was nearly twice the .041 spec of the new plug on the left. The engine purrs like a lion at idle and screams like a tiger at WOT with no hesitation.

Gap aside, they look pretty good for 130K.

Any issue getting them out?

I'd be surprised if there was on an '11. That problem was overcame after around '08 MY trucks...head redesign and a move to one piece plugs.

If you've seen a few, you can tell at a glance that those he took out are the later design. Hope this helps

Any issue getting them out?

The ones in the back tend to pick up moisture, so a little rust penetrant may be needed to loosen them up a little. You can crank down on the 1-piece plugs pretty hard without them breaking though.

They are the new spark plug design so no issues getting them out. I put anti-seize on the new ones so when I change them out in 60k, there won't be any issues.

I just don’t like buying cars w obvious deferred maintenance.

What do you recommend for my 2011 XLT? Hot or cold plugs?

 

[RobE]

Use the Motorcraft OEM plugs.
