Well that's the engine I have, 4.6. LolWell, don't use that part number if you do. (That's for a 4.6L car motor...).
I would recommend the OEM Motorcraft part:

If you're going to all the trouble to replace it, use the best parts available. Replace that heater hose under the manifold too while you're in there.

Coolant level is good. Never had to refill it. It due for a fluid change though. So I'll just find a good time to remove the intake and replace the gaskets. Thanks for the advice guys.Most likely you only need new lower intake gaskets. They are pretty cheap and not to bad of a job to replace. Wouldn't waste my time getting a new intake until the old one is off and inspected. 90% of the time the intake is ok but sometimes the aluminum crossover pipe can corrode pretty badly around the gasket surface so if it's been slowly consuming coolant you may have to replace that while it's apart or sand it back to flat and smooth.
