I am new to this forum. My first ford. 2008 f-150 5.4 45,000 miles.
I like changing the plugs around 50,000 miles. I started taking off what I thought was the coil maybe? But it feels like it is attached to a rubber boot? Not sure. I have changed plugs in all my vehicles but this is different and need some direction. Will I have trouble getting them out? What type of plug is it? Appreciate any help.
Thx
