The spark plugs in my Zetec Focus are all the same. Is your son's name Hugh?
Well, I thought I'd seen it all but...
I went to change the plugs in 2000 SE. On removing the plugs my son
commented, "why do the plugs have two different colours on the end", to

end of the plug while the other two had red paint. To further confuse
things, numbered from left, 1 thru 4, 1 and three were white while 2 and 4
The white capped plugs have a part number AGSF34E.
The red capped plugs have the part number
Can anyone enlighten me about what game ford is playing here?
I have installed four Champion 3407 Platinum Plus plugs and it seems to run
fine. I can't see any lenght difference in the Motorcraft plugs.
Thanks for any help shedding light on this.
