what spark plugs should i use? i see 2 motorcraft models and i want the best ones. its a 2003 5.4 AGSF-22F-M1 AGSF-22W-M

 

What? Seriously? The trucks been out for 10+ years. Google man. Google.

SP-479 AGSF-22W-M

 

Thanks tackle. i was trying to see which ones were which before i buy them.

 

'06, eh? Hope it's not as hard to do as my '02 was (hey, tackle, I finally did them!). I'd get the same kind that came from Ford when new. They're good plugs.

 

The have the spark plugs recommended for your Truck in the owners manual. They also have the fuel filter, oil filter, air filter, and a few other maintenance parts.

 

yeah but i was looking on a website that only had the part numbers and i couldn't tell which were the right ones.

 

Time to wake this thread back up I need as many of you smart fellers to explain how to change the plugs in a 03 5.4 like anti seize and torque specs and that they don't break off. ( in case my dad decides I'm doing it wrong ) because he thinks they are all 3v's and break off. And that 28-32 LB FT. Of torque isn't way too tight and that the SP-479's have nickel plated threads so they won't corrode to the aluminum heads.

 

Yup you got it right. Tell Daddyo to go inside.

 

Still gonna need at least 5 or more of you guys to chime in to convince him you all aren't idiots on the Internet. ( as he thinks Internet is always wrong..)

 

28-32Ft/lbs per Ford TSB. SP-479 or NGK/Denso Iridium's as far as plugs go. 2v's dont have plugs that break.
