Looking for a used (in good condition) intake manifold 2004 or later for the 6.0L. There are two types and I am looking for the one that does not have the rear casting...basically the U shaped...if anyone knows or has one PM me.
I took mine to a machine shop and had it cut and tig weld aluminum plugs, this was a simple fix, cost about $35.00. For an extra $30.00 had the EGR cooler plugged both ends with stainless inserts and welded also. If you change the intake to an 05 or later you have to change EGR cooler too. Cutting the bridge cross over out allows for the intake gaskets to seat better and I appear to get better performance. Mine is a 2003.
Below is a breakdown of part numbers of all available intake manifolds for all applications of the 6.0L diesel:
3C3Z-9424-AJ
(For 2003 to early 2004 model year F-Series)
4C3Z-9424-E
(For late-build 2004 F-Series and 2004 E-Series)
5C3Z-9424-C
(For 2005 to 2007 F-Series and 2005 to 2010 E-Series)
To Joe Blow, if your truck is a late-build 2004 with the ICP sensor on the valve cover, the correct application you require is 4C3Z-9424-E. Hope this helps.
