Its official the 2valve pi manifold has ceased production.

SO what is the purpose of the insulator blanket on the bottom of the Vic intake?

If it for heat insulation? Or NVH?

Im debating if i install it, or just leave it off.

EDIT: Most internet searches imply it's more for sound insulation when at WOT. I'll leave it off.

That is a towncar, crownvic, marquise sound insulator. Im sure using it would help with repelling heat from soaking the manifold.

 

[Mustang5L5]

Decided not to run it.

 

[Mustang5L5]

Well. Looks like Ford found a new manufacturer for the “PI” intake.

Zoom in on the far side…

 

[07GtS197]

Where did you buy that? How are the runners compared to the pi intake? It looks like a rebranded Dorman.

 

[lwarrior1016]

That uses the self tapping screws for the fuel rails, just like Dorman. What does the gasket look like?

 

[lwarrior1016]

I see fomoco, but no ford casting number.

 

[Mustang5L5]

Not my intake. Popped up on FB. Apparently all the “backordered” intakes have begun shipping.


It’s a FoMoCo branded Dorman?? intake.


EDIT: At this time i'm assuming it's made by Dorman due to the runner design.

Oh, that really sucks. That’s what I was afraid you were going to say.

I’m curious whether the pi intake was patented. I’m sure the bigger factor to manufacturers not making them, though, is that it’s more expensive than the other crap out there now. I was looking into the trickflow intake as the streetburner intake has runners close to the same length as the pi intake. But it looks like they’re out of stock so I’m guessing trickflow is cutting their intakes too. That just leaves used intakes, crappy aftermarket and Edelbrock.

It’s the method of manufacturing. The Dormans, I believe, are molded in sections and then sonic welded. The original PI intake is made as one piece with a sacrificial internal mold that is melted down. It’s that particular method that allows for the deeper plenum “plunge”

At least that’s my take on it given the info 96blak54 has offered up.

 

[Mustang5L5]

Box it came in. Looks like it’s a new part number

PU7Z-9424-A




Can’t actually find one for sale. Found one on eBay and this was the listing info for product usage.

 

[07GtS197]

Wow so, like other parts, the pi intake is now supplied through Dorman. I guess that makes sense but that’s a huge bummer, especially at that price. I guess I’ll be on the hunt for some used pi intakes now.

 

[lwarrior1016]

I’ve got a PI intake that I bought brand new from the dealer in 2019 ish. I think it’s got 40k miles on it or so. It’s on my town car that I am getting rid of. I’m going to swap the intake out for a Dorman intake. So I’ll have one I can let go of. Won’t have it for a few months but I’ll have it off soon.

 

[07GtS197]

I don’t know if anyone else has asked but if not I’d be interested. I have a junk Dorman on my 03.

 

[RAU03MACH]

sounds like there in rush to push out whatever
lots of backorder

Exactly! We in the factory dubbed the production line "loss core". Supposedly only 2 facilities in the world had this production. I believe the company owned both and the patent process. Now this factory no longer has this process.

 

[Mustang5L5]

So long story short, the Dorman is all that exists now, and you'd be stupid to pay the inflated pricing on the Ford unit and might as well get the reboxed Dorman's on ebay for $100 since it's all the same.

 

[SnakeBit!]

That stinks Ford is doing that, but I get it. makes me even more glad I bought my extra PI intake from Summit long before all this happened.

 

[Mustang5L5]

Interestingly enough...i can't actually find part number PU7Z-9424-A for sale anywhere.

There's one i saw on FB, and one completed auction on Ebay. Looking at the different Ford sites. Nothing.
