Has anyone here with a later model v10 ( 2007,2008, 2009 in an F250/F350 ) when changing spark plugs found that Ford had installed the updated one piece spark plugs at the factory? I have an 09 and have been led to believe that to be the case, I have 89,000 on the odometer and am getting ready to swap out the plugs for the first time....I would like to know if that is the case so I can have the correct plugs for my engine on hand when I do the change. However, since I have never really heard of anyone confirming this...is it maybe just a myth?

 

When I replaced mine,they were the updated plugs. I think the boot color changed at that time.

 

The engines received the factory update in Mid 2007 builds, the area around the plug was also increased.

 

Thanks guys, I can see that my boots seem to be a brownish rust color and not the black ones so mine are probably the updated plugs....do you have the part number for the new plugs by chance? I'm 40 miles from the nearest parts store and would like to have the correct plugs on hand before I start the swap.

 

That was my understanding too, I remember people saying that as of 2008 model year, they were definitely switched over.
