This ad says that the manifold is for a 99 and newer 4.6, but it doesn't look like a PI manifold to me. (the runners are too straight to me) What do you think?

PI or Not?

NPI!

The first runner goes to the passenger side head and it has the NPI coolant crossover.

I would guess PI, a couple of people here and on Crownvic.net have asked about it, they look funky, and the NPI ones (that the list, there isn't a good shot of anything that makes it easy to determine) look similar. It isn't the OEM one, and it isn't made by Dorman I don't think.

The first runner is a tell tale of which intake it is. The PI intake's first runner goes to the driver side head, the NPI intake's first runner goes to the passenger side head. The picture listed CLEARLY SHOWS THAT!

I was thinking NPI myself. Just didn't look right. Glad I got an education here before buying anything.
