    Do I have the upgraded intake manifold?

    I come from fox bodies, so I'm new to the 4.6. I'm wondering if my 04 has the upgraded manifold? Under load on the freeway it gets a little bit of shaking like its motor mounts, but it seems solid at idle, any ideas what it could be? Heres some photos of my manifold. Thanks
