Q: Anyone w/ 06 expedition or I guess any 5.4 liter ford has compared them with platinum or iridium doubles plasma? Im looking for performance

I own a 2006 Ford F150 5.4 these plugs is absolutely fantastic the power performers is greater the fuel mileage is great I recommend these plugs to anyone that owns 2006 Ford F150 or expedition

Q: Is this spark plug one one piece? The motor craft ones are 2 pieces that break when they are taken out.

Terrible luck with these. Kept loosing cylinder power due to the porcelain cracking. Pulled 2 out in less than 2 weeks then replaced them all. Went back to Motorcraft ones.

Q: I have a 2007 sport Trac v8 and bought these with a 5/8 socket but I can't get my old plugs out with the 5/8 so wondered if I need another size or if the one in my truck are different.

i know this is old but i'm answering to help others since i just figured this out last night. you want a 9/16 not a 5/8.

Q: is this spark plug colder than motorcraft sp515?

I believe they are the same. Be forewarned..I out them in my 2004 F150 with the 5.4L 3 valve. After about 1000 miles, I started having problems and intermittent CEL. I swapped coils around and just drove myself crazy. I ended up changing the plugs on a whim (last resort) and no more problem. I have put on over 5000 miles since I changed them out to the 515, and the truck runs great.
