I have an 03 6.0 and according to ford the correct part# is 3c3z6k854da. However according to a couple of sites several other part #'s work including 5C3Z6K854CA, 5C3Z6K854BA, 5C3Z6K854AA. Does anyone know if there is any real difference between these parts. The reason I ask is that of course as luck would have it the ford recommended number is about $100 more than the others. From the pictures they all pretty much look the same. The only difference that I can see is the first one mentioned seems to have some add'l heat shielding. Does anyone know definitively what will and won't work on my '03

 

Nothing on this one. Man I was sure hoping for some direction here.

 

Go look at
AutoNation Ford White Bear Lake Parts (previously Tousley Ford Parts)
Maybe you get get the one they say is the correct one for less.
They are a sponsor and have some really good prices for us.

The 03's have a different EGR cooler and the connection is different at the up pipe IIRC. If that part of your y-pipe is still good then I think you'd be able to use any of the pipes for parts. Where is yours broken?
