For the derps like me, can you explain why this is a bad thing?It’s a rebranded Dorman, manufactured by MPI. Don’t get swindled by this scam intake by made in USA and FoMoCo being molded into it.
I don't know about Derps like you, but for Derps like me running a PI intake on NPI heads, I don't think the coolant ports can seal properly the way the actual Ford part does.For the derps like me, can you explain why this is a bad thing?
Requires intake manifold gasket set 4C2Z-9439-CC available from your local Ford dealer
I bought a kit from a Ford dealer that included gaskets for around $240 about five years ago. I see the pictures they have posted. It sounds like they are going to dyno it so it will be interesting to see what they get compared to the real PI. I'm not ecstatic about it, but at least there is something that I could use if my intake blows out tomorrow. Right now, my only quick option is Dorman NPI intake manifold.On the LMR instagram page it has pics of the underside; short valley runners and integrated gaskets like the Dorman. It’s literally made by the same manufacturer ford is contracting, the tooling to make the real deal PI intakes was destroyed.
There’s a 10-20 horsepower loss from a OEM PI to a Dorman and many know it, because it is essentially a npi intake with PI ports. LMR and Ford Performance seem to want to hock it for a ridiculous profit, adding some feelgood Ford and USA text to the mold isn’t exactly fixing the flow issues.
BTW anyone remember what genuine FRPP PI intakes used to cost 15 years ago?
$185.
I was thinking I got the whole kit from Nick for ~200, tubes and all.
Well I think we all know Greg is not a normal person.. but we love him!!!Or you could use a pry bar or flat head screwdriver to take it off like a normal person.
"Love" is a subjective term.Well I think we all know Greg is not a normal person.. but we love him!!!
I thought only the non pi aftermarket intake manifold sucked. Would a aftermarket pi intake be better for a non pi 4.6 then a aftermarket non pi intake for better performance?
I don’t understand why they can’t make a decent manifold, I don’t think making a piece of plastic that can get good air flow is rocket science. If someone can make one that can get good airflow #’s they would sell like hot cakes. So does both the pi and non pi both suck? I thought only the non pi aftermarket intake manifold sucked. Would a aftermarket pi intake be better for a non pi 4.6 then a aftermarket non pi intake for better performance?
I doubt in CA that would pass smog, I love my V8 but my SC has much more options from a performance standpoint living in CA.
Good to know. Although that seems like a major loophole for anyone selling performance parts to just market them as replacement parts, but then I really shouldn’t expect a government bureaucracy to make any sense.Doesn't need CARB certification when it's a direct 99-04 "replacement" part.

I did just watch LMR’s video on it. As expected, it is down about 10hp up top, and about 20 ft-lbs in the midrange compared to the real PI manifold. However one thing I see that I do like is they finally have the aluminum crossover mounted such that coolant is no longer going through any plastic! That always pissed me off that Ford knew coolant going through plastic was a problem and went to the trouble of redesigning it to incorporate aluminum, but still decided to leave just enough plastic to make it still a problem, just not their problem! Fucking assholes! With the new one having the aluminum crossover sealing directly against the heads, I would say for anything where performance is not a major concern, I call that a win! I have refused to use the Dorman or other Chinese manifolds because of the cheap plastic, and in my experience they only last a few years, but for the next panther platform that comes in my shop with a leaking manifold, I’m glad to have this as an option.
