A friend of mine owns a 2010 F150 lariat, with the 5.4L.

He wants to do a plug change, and just wanted to make sure before he starts it's a straight forward remove and replace job.

I just did the change on my 2006 5.4L and it was a beast with the breaking plugs(every one broke) and so forth, is the 2010 no issue?

 

No issues for the 2010.

 

The heads were revised in 2008, the 2010 has conventional style 1 piece plugs.

 

Enjoying my 2010 Platinum I've had for 6 months, but has 112K and needs plugs.

Are the Motorcraft SP-509 the plugs I need for replacement?
I also want to keep a spare coil in case, what is the Motorcraft stock number for that?

Thanks

 

Yes, SP-509. Coil is a DG-521.

 

Thanks glc !!!
