Does anyone know how to change spark plugs on an 09 XF Supercharged? With pictures if possible.

 

I don't have photos, but it is a pretty straight forward operation on the 4.2 supercharged. One plug per cylinder and each plug has an individual coil attached. I just went down the line and pulled/replaced each. I did need a variety of extensions and a hinge for the ratchet to get the ones closest to the firewall. They can be a little tight to get to, but with patience it can be done. Took me about an hour and 45 minutes which included my having to fish a dropped ratchet off the belly pan when it slipped from my hand.
I'm told the 5.0 plug replacement is a whole different ballgame.
