2008 F150 Spark Plug Change

Well after researching this project for a couple weeks I finally got the time over a 3 day weekend to attempt the change.

I started yesterday but putting some seafoam into the vac tube and the rest in the tank. I also put some pb blaster in the spark plug wells and then cracked each plug slightly to allow some penetration. I then let everything sit overnight.

Well this afternoon I actually put the packs and everything back on an tried to burn off some of the carbon before attempting to take the plugs out completely. After getting the motor warm and letting the white smoke go away I started the plug removal. After several pucker factors all 8 came out without breaking and I had the oil changed and everything back together by about 4 pm. I took the truck for a 1 hour drive to make sure that everything was working right and I am happy to say this is done.

Now I think I benefited from the truck only having 22000 miles on it ( I ride a motorcycle most of the time). So even though it is almost 6 year old the carbon had not had time to build up as others have experienced. The plugs did have a decent amount of build up (I will post pics in the future) but letting the seafoam soak overnight seemed to make it soft.

Just thought I would share the experience.

I think your 2008 has the new style plugs that are 1 piece. But, either way kudos for doing it yourself!

Not sure but I think the ones that were one piece had the brown boot and the early ones had the black boot, I have the black boot. So I think it is the old design.
