I just changed my spark plugs in a 2007 Fusion SEL V6. It was very easy to do with a minimum amount of tools and knowlege. I installed the Bosch Fusion 4+ Platinum (gotta like the name of them) and you can really feel a difference. The car had 173,000 km on it and I did not feel a need to change the original plugs but I had heard of them getting seized into the block after 100 - 150K so I was way over do. No problem changing them at all. You need to loosen (you cannot remove them from the manifold completely as they are secured to the top portion which is good as you will not loose them) the 8 screws that secure the intake manifold to the block. I also removed the two hoses that connect to the intake manifold at the top near the firewall and the electrical connector on the passenger side of the manifold. There is also a silver device mounted on a bracket on the driver side of the manifold; I removed the 2 bolts that secured it and then I was able to hold up the manifold enough to gain fairly easy access under the manifold from the drivers side to get at all three plugs with a ratchet. No problems at all. While I was at it I cleaned and oiled the K&N air filter and the car sounds and performs like a bat out of hell! So far this year I have done the plugs, installed four new Riken Raptor tires and EBS drilled brake rotors and pads. Mark
