My intake manifold for my 03 4.6L started leaking coolant at the thermostat junction with the intake manifold. Looks like it is a common problem. But the part is not in stock anywhere and no one has an ETA.

Part # M-9424-P46

Any alternatives besides Dorman?

Also there is a place on ebay that has them. I just checked 250.00 there based out of Maryland. Search 4.6 intakemainfold mustang gt.

dorman is one of the best because it has the lowest risk of spraying coolant into intake holes.
