So, thanks to this video, I found out today that my mustang I drive everyday has a doorman, and the mustang I have sitting in the junkyard has a performance one on it. I was wondering why my Boltons made me feel like I was competing with my old one stock. Looks like I'm spending this weekend getting an extra 20 hp hopefully. Great video.
Do it with the typhoon full aluminum intake manifold. I want to see what it can do. I got stuck getting a Dorman. I got it on rock auto for $65 with express shipping included. So I got a super steal but now I realize thanks to your video I'm being robbed of horsepower. I wish I had knew this 8 years ago 😪
Hey lmr love the video. But as someone from the new edge community I think a big hit you could do for 2vs is manufacturing a new intake to compete with Logan style intakes, Victor, typhoon etc definitely not many options out there
Found out a while back that the Dorman was complete trash. I had a leaking crossover pipe on my 05 town car. Went to the local salvage yard and grabbed a Dorman unit off of an old taxi. Once installed it had terrible throttle response. Definitely was not the same car. I ended up buying a replacement intake manifold from 1A auto. It actually was dang near identical the original ford part. I installed it and the throttle response was back and I save a couple hundred.
I have a 08 4.6l F150 That I just bought a dormant intake for. It was warped, So I have a mighty vaccuum leak. I think I might just try to return it and get the 1aauto part. I'm so sick of fighting this damn thing
@@countryboy9546 for some further clarification the Dorman unit has short runner design. The OEM has the longest runners but the 1A auto comes dang to the factory runner length.
@@mattmccoy2410 yeah, I was looking at that. I see the short design in photos online of the Dorman intake. You must be talking about the TRQ intake which does seem to lend itself to having a longer runner design. I’m hearing Dorman has changed their intake design and has improved it their most current intake vs the old part.
I run the Dorman intake, because the Ford one was out of stock :/ I did not appreciate the self tapping screws-but honestly everything else was very convenient. The Dorman intake is a KIT-cost about 200$ for the intake manifold, the gaskets, thermostat, o-ring, and hardware. After install, I did not notice a real difference in power-except for smoother engine operation. I’ve been running it on my car for a year, and it’s been good to me so far. I’m very surprised of how much the Dorman affected this car.
@@juansabal9995I just had the Dorman intake installed on my 99 GT with 72,000 miles and it’s running awesome. I didn’t lose any power going from the factory intake to the Dorman. The engine runs so strong and smooth. I’m impressed.
@@Ornelas11B i loss something like almost car length with my neighbors car, previously with the oem intake I was ahead of him..!! The difference you will notice is only at wot
in my opinion both are garbage plastic or composite material that crack, i bought a new ford racing one, it only lasted me 5 years before cracking. now i'm thinking about just throwing a cheap dorman one on, at least i can buy 3 of them for the same price that the ford racing costs in todays post-covid parts shortage world. i see these dormans go for a 100 or so on fb marketplace
My 04 mustang GT intake manifold cracked and my mechanic told me he would put the best that money can buy because that’s what I wanted and I wanted to keep the car original with ford quality parts and he put a dorman intake on and said it was from ford now I got to do it right myself
@@NoNo-iz8hd I've encountered plenty.. i had white smoke coming from my exhaust n a dyno shop told me my pistons were worn, $5k in labor to replace + parts.. Took it to another shop, turns out it was a cracked intake manifold n leaky fuel injector.. Honesty goes a long way, now i'm a repeat customer of theirs.. They installed my TFS 38cc heads n cams, rear diff fluid change, n i recommend them to everyone i know n asks for recommendations.. Gotta be careful who we trust our cars to..
The pi intake from Ford is cheaper and flows more. The dorman one actually flows less than a non pi intake and it is the same as installing a check engine light.
I believe you are right because every since the mechanic installed the dorman door knob on my 04 mustang GT the check engine light stay on and he clear the code and it comes right back on but the car is still running good but I can feel a power lost on top end and down low
Ford intake- part # PU7Z9424A it’s a direct replacement for the original. It’s says it’s out of stock… I called the Ford dealership here in Spring Hill FL. Asked for the parts department, told him I needed an intake manifold for my 04 Mustang GT. He had the intake sent to me the next day! $425 it works great!
That's great! Glad you got one. That same intake is about to be in stock from Ford Performance. It'll be around $349.00 (pricing subject to change, of course). -Landan
I replaced my doorman intake manifold with the ford PI intake and add a 70 mm throttle body and hello and good morning or night and day difference on my 04 mustang GT automatic
This makes me very mad, when i bought my car it had the dorman intake. I feel like i've been cheated, but I'm gonna be getting a Kenne Belle so I guess the gains will be even better
What he really did not do is describe exactly WHY the doorman is a poor choice and a non performance intake. When ford redesigned the 4.6L and came out with PI heads cams and Intake the PI intake has larger runners. Dorman had already made the 4.6L replacement manifold and instead of redesigning a new PI intake for the PI engines they kept the same NPI restrictive runners from the original design and just changed the last 2-3 inches where it bolts to the heads with the newer PI design. so when you buy a doorman PI intake for your PI application you are simply getting a NPI intake that bolts up. Avoid this turd even if given to you the dyno clearly shows that it is a poor alternative.
Just put a Dorman on my 97 Thunderbird, thermostat that came with it failed immediately and engine got hot. I put the old thermostat in and so far so good.
My car had a ugly missfire on cylinder 1 and 5 when I bought it. Turned out the intake gasket was letting coolant pass through into the runners. So I bought a Dorman at Orileys because it had lifetime warranty.. At first my car ran great, gas efficiency was way better and the miss was gone but after awhile the miss is back. I replaced the coils,plugs,fuel filter,cleaned the maf and it's still missing so im betting its that Dorman intake failing again.. Going with Ford next round..
Ford racing PI OE intake manifold, plus long tupe headers 👍 on a P-71 interceptor 4.6 liter from 2 inch dual exhaust with H pipe to X pipe with 2 1/2 inch dual exhaust swap , which helps equalize exhaust pulses at higher RPMs (327) rear end gear ⚙️ ratio. I need them gains, then increase throttle body diameter and true cold air intake.
Of course the FRPP intake is sold out everywhere and people are asking crazy amounts for used OEM units. Just sucks. My car is FBO, tuned, geared and I know I am losing a good amount of power because of this dang Dorman manifold. Makes me sad.
Changed a many of these on Crown Victoria's, and those screws are crap! The OEM(if available) or the Authentica brand is the best bet. I got so good at changing those intakes I could do the complete job, and have the customer out the door in 20 minutes using no battery powered tools. If Dorman was what they wanted I would put a thin film of gray RTV around all the intake and coolant ports to prevent leaks, as I had one leak coolant at the rear from the improper design.
I just put a TRQ stick replacement on my 97 MGM non pi engine but it seems like a good product. Been driving it for a out a week now with no problems no leaks. I think even though it's a stock replacement it could make a little less than the stock intake just due to car being stock everywhere else. I did clean and somewhat polish the plenum and throttle body. It does have a lag some I'm the lower range but in the higher rpms it seems just like the stock one as far as I can tell. The lag may be the air fuel ratio and I would have to get it tuned for that
I have a dorman on my 98 MGM for 8 years now, almost 100K. Just needed a part delivered the next day so I can install and go. Don't really care about extra power but it may get a bit more gas mileage with this intake. These years must be modified a bit to take the Ford Intake, didn't want to mess with it..
TRQ and dorman manifolds are trash Imo I've seen 3 of them fail within a year, either huge vacuum leaks or coolant leaks... Poor quality control I guess
There isn't an updated link at the moment. I made our marketing team aware of the issue. They'll work on fixing the link so the old product page can still be viewed. Thanks. -Landan
Just put a dorman in cuz i couldnt find a ford one. I was searching for a fix for my lean condition code ended up being my fuel pump. But apples to apples, i felt my explorer with a 2v running a little better on the dorman. Also visibly from the exterior the runners look bigger but shorter than the Ford one.
Geez. Idk how the ASE haven't banned the Dorman intake from use in repair shops. That's almost criminal. How can you call a replacement part something that leaves it worse than during the original failure?
I'm not 100% certain the power loss is as measurable on a stock car. That car had high flow exhaust and 93 octane tune, so I could imagine the air intake capacity could be a lot higher than stock. You might get a power loss with boltons, but not necessary with stock intake, cats and exhaust.
@@P71ScrewHead They don't make the PI one anymore, and the trickflow requires additional modifications, suffers from heatsoak and doesn't give the same powerband either. Even the Ford PI intake is going to split again.
juan - We're splitting hairs when it comes to the manifold designs for 96-98 and 99-04 cars. Both are a log-style design with not enough differences to see a noticeable power increase/decrease. -Landan
And now it looks like the manufacturer who made the PI intake has ceased production. No more Ford Performance manifolds to be found. What is one to do if stuck with a Dorman and down ~20HP?….other than Coyote swap 😊
Heard a rumor that the Ford Racing PI intake will no longer be produced. Checked LMR's site and its out of stock. Is Dorman our only option now for a new plastic intake?
Rumor - "A currently circulating story or report of uncertain or doubtful truth."

When the nipple for the heater core broke on my stock manifold.I went to Ford and bought a brand new Ford Racing manifold never run that crap dorman it doesn't run right with it 23hp lose no thank you. These cars already make low hp to begin why run garbage..
Ive worked for Dorman for 6.5 years now and am restoring my fox with a mix of LMR and Dorman parts. When I saw the Dorman name on the video I got pretty excited. Super cool to see the dyno results!
@@robsorgdrager8477 i deal with steering and suspension mostly. But its things like this that we need to see to make sure our parts meet the right standards. Regardless… i made sure the right people saw this video.
@@bmaccccc9 I ran into issues with these when building my Vic and then started seeing the exact same issues on my customers cars. The air fuel actually freaks out to the point of causing misfires at highway cruising speeds. I swapped the dorman out for a fomoco perf part and AFR almost instantly plopped back into spec and fuel trims came back to normal. Normally I use moog or dorman as I have learned to trust the parts and most times the dorman parts are better than the manufacturer. As a mechanic I understand that sometimes stuff happens and it's to the fault of the universe. I would assume if dorman fixed the runner cross section it would be equal to if not better than the Ford part.
@@robsorgdrager8477 before dorman i was a tech myself and 100% understand. When i started there it was refreshing to see what they really do to fix anything they put out there that isnt meeting atleast OE standard. If you are interested… we have a facebook forum if you want to join. We talk parts, issues with our parts, what you liked and what can we improve. Techs do voice their oppinions on our parts which is not always positive, but its a great learning experience for us to improve and fix whats out there if we were not aware of it.

Ive worked for Dorman for 6.5 years now and am restoring my fox with a mix of LMR and Dorman parts. When I saw the Dorman name on the video I got pretty excited. Super cool to see the dyno results!
Are you to blame for the less than " lack luster " performance.
@@robsorgdrager8477 i deal with steering and suspension mostly. But its things like this that we need to see to make sure our parts meet the right standards. Regardless… i made sure the right people saw this video.
@@bmaccccc9 I ran into issues with these when building my Vic and then started seeing the exact same issues on my customers cars. The air fuel actually freaks out to the point of causing misfires at highway cruising speeds. I swapped the dorman out for a fomoco perf part and AFR almost instantly plopped back into spec and fuel trims came back to normal. Normally I use moog or dorman as I have learned to trust the parts and most times the dorman parts are better than the manufacturer. As a mechanic I understand that sometimes stuff happens and it's to the fault of the universe. I would assume if dorman fixed the runner cross section it would be equal to if not better than the Ford part.
@@robsorgdrager8477 before dorman i was a tech myself and 100% understand. When i started there it was refreshing to see what they really do to fix anything they put out there that isnt meeting atleast OE standard. If you are interested… we have a facebook forum if you want to join. We talk parts, issues with our parts, what you liked and what can we improve. Techs do voice their oppinions on our parts which is not always positive, but its a great learning experience for us to improve and fix whats out there if we were not aware of it.
@@bmaccccc9 that's actually pretty cool. I my giver a look 🤙✌️
