I'll take the blame for not double checking but the parts store gave me two different boxes of plugs and I didn't realize until four were already in motor. The ones in motor are motorcraft are sp485 and the others are sp479. Which are supposed to go in an 02 f150 5.4?

 

sp479 are the replacements and are good.

 

That's my luck. Time to grab a beer and retire for the night.

 

Make sure you do NOT use antiseize and torque them to 28 ft/lb.

 

glc,
thats the plan I went with.

 

Good strategy
