4.6 plugs vs 5.4
I have a 97 4.6 auto 4x4. In looking at the
NAPA site the picture of the plugs looks normal
with the long thread.
I looked up the 5.4 plugs and the same picture
was shown.
I thought the 5.4 plugs were the type with
the long electrode shield that much talk has
beengiven on removal problems.
Is the 4.6 plugs more like the old style?
With no problems on removal?

Here is the scoop on plugs. All the 2 valve engines use the same type of plug. It is the conventional plug that we are all used to seeing. The 3 valve engines have the long ones. Some of the 2 valve engines prior to 2003 may experience a plug blowing out of the head. Some of the 3 valve heads have the plug breaking while removing the plug. You can do a search and read all about these mishaps.
