Need to replace intake manifold... what to do...?

[The Deuce]

First let me say, yes Ford will take care of that for you, no questions asked.

Now then, you're screwed on intake manifolds. There's the Bullitt aluminum one, Saleen has one, and that's about it. They're both in the neighborhood of $1,800. It's because of their shape that it's so expensive for people to make them.

The best plan would be to get the Motorsport intake and heads, and get the heads ported. That'd cost probably three grand to do, so go get lucky at the craps table after work.

Other than that, call the Ford dealer and make sure they'll take care of it for you, then save your $.
