Guys gonna charge me $150.00 to change my spark plugs. He has the SPARK PLUG TOOL to keep from breaking them. Is this a fair price ( plugs not included, I have those )?

 

if you think the guy has the skill/experience to do it that's a very fair price. Imagine doing it yourself and you break any one of the plugs....

 

He use to work at a Ford dealership,

 

You should do the coils while you are at it, he is going to be there taking them off to do the plugs anyway. Very good price.

 

I have a 2004 with the single piece plugs. I changed the plugs and coils without any real issues, just some grunt work and the requirement of numerous robble sockets, extensions, etc. You also need to remove a lot of incidentals to provide good/easy access especially back at the firewall.
Well worth the effort when you consider the savings with having a dealer do the work.

Good luck.

 

Most any place would charge you $400-$600 to change them, more for any that break. I suggest you spend the money and get the OEM plugs (Motorcraft SP493, SP-493, AGSF32PM). They're good for 100K miles so it's not worth using cheaper ones that might fail or not last as long.

 

If it's a '05 Navigator, it has the same 3V 5.4 as the Expy, which means he needs the long SP-515 plugs. And be sure to put some anti-seize on the long neck, and a dab on the threads to avoid future issues with breakage. Just don't get any anti-seize on the ground strap or electrode.

 

Truned out to be a cam phaser and solenoid. Plugs came out easy!!!!!!!

 

I wouldn't touch a Motocraft sparkplug again if you paid me. Go with a Champion 1 piece plug.

 

The replacement MotorCraft ones are now 1-piece.
