foil delete?

[bigf350sd]

Hey all, Ive seen a few members on here whose list of mods said foil delete. Ive done the zoodad mod, about to do the harpoon mod, but havent heard of the foil delete. What is it and what does it do, and what model trucks does it work on? Anyone?

Huh...must be the foil that wraps the down pipe on the 03 trucks.

No, I think from his post on PSN he is talking about the hot side intercooler tube. I guess it is foil on the 7.3 he got alot of hits on that over there.
