Not of which I am aware, curious as to what they would say that?
That said, I would not use the Dorman PI intake under any circumstances--temporary or otherwise. It is a non-PI lower section and runner configuration with PI manifold flanges, sort of a Franken-manifold they created by mating the lower section mold from the non-PI unit with a new "sort of" PI upper section.
When the manifold on my '03 failed I bought a Dorman and brought it back within 30 minutes. It is also a one-size-fits-all replacement for the various 4.6L 2V configurations and will not allow use of the stock generator bracket, you must use the ugly universal fit thing it comes with.
Get the FRPP manifold, you will not regret it...
