2006 E-250 5.4 spark plugs
Just bought an 06 E-250 with the 5.4 I am hoping the plugs were changed around 100,000 but not sure. The owner lost that receipt from the garage. Van is at 160,000
What plugs should I use? Autolite, Motorcraft, and even heard a champion?
I plan to change these every 50,000 depending how long I have the van.
