Consumer feedback highlights a mix of experiences with the product. Many users have praised its quality and performance, with comments like, "my car instantly ran a million times better," showcasing the positive impact on driving experience.

Quality looks good. From all I can tell everything worked out pretty well.

Positive Feedback

If it's smaller I'm pretty sure it does mean it's robbing power in comparison, how much would the difference be?

Areas to watch—feedback on possible improvements.
Potential power loss with aftermarket intake manifolds
If it's smaller I'm pretty sure it does mean it's robbing power in comparison, how much would the difference be?
it might just cost you a little top end power.
they’re dyno proved to rob like 12-20hp but they’re much cheaper.
you might lose 5-10hp. However with Ford discontinuing the oe one you kinda gotta roll with it.
Potential power loss with aftermarket intakes
You absolutely do lose horsepower with a Dorman manifold. It's been proven.
the Dorman intake manifold is literally the worst thing to ever be made and I'm ashamed it's still around.
So I should still be covered even by the original limited warranty anyways.
Introducing new failure points with aftermarket intake
I did the swap a month ago and it was worth it completely.
And that manifold will do nothing without the corresponding tune to activate/tap into the DISA valves.
Aftermarket intake may be inferior
We need someone to make an affordable aftermarket replacement that isn’t terrible *cough* DORMAN *cough*.
No performance increase with this manifold
Is the red aluminum intake manifold worth it? I have a 2016 FR-S that uses the black, plastic-ish in
No performance increase
High cost for minimal performance gain
But I wouldn't spend $480 in parts + $500 for a tune to get 3hp.
It could be under warranty because it's in the intake but I think premium care is 'internally lubricated parts'.
Requires a tune for performance increase
Anything that makes actual power needs a tune.
Complexity in installing a new ECU for performance gains
You’d need to install a 2017 ECU to have a chance of getting any value out of it, which is a lot more complicated.
Claims of real HP gains seem dubious
However, claims of any real HP gains seem dubious.

Core Power Plays

The specs and strengths that make it shine.
Discussion on aftermarket parts and their performance
dorman is a fine company and make good parts.
New Ford racing intakes are not available and nobody knows if or when they will be.
Discussion about intake manifold temperatures
Is there a range I should be on the look out for during the summer for the intake manifold?
it’s a great product if you’re concerned about temps when accelerating under load.
Aesthetic appeal of intake manifold matters to some users
It looks cool though and thats what matters.
Discussion about aesthetics of intake manifolds
I don't know what it may do for performance but it looks wayyy better.
Discussion on power gains from aftermarket intake manifolds
The gains are pretty well documented and not just JDM bling.
Is it noticeable?
Fascination with the events surrounding the GR Corolla fire
This is honestly fascinating to look at, I might have to show one of my coworkers and get his take on it.
Discussion about gasket sealing surfaces
I recently Got a kinetix plenum and put a metal paper plenum gasket on, had a slight vaccine leak after tightening all bolts.
Since you’re adding another sealing surface, you most likely need another gasket.

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion about tuning for aftermarket performance
That's why you get it tuned.
the tune is nothing crazy but it does take some research and willingness to find the right software and procedure.
the tune immediately bricked/blew out my vanos.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Tips for working on the intake manifold
Dorman manifold gasket leak. Bought summit racing one to replace.
Alright alright jokes aside, it's a pretty easy job.
I'd personally recommend an electric drill with a stiff plastic scrubber brush attachment to clean the surface between the head and the new manifold.
Then we saw it and stared at it for a minute and decided 'It worked without it'.
Discussion about compatibility of intake manifolds
I would assume an increase since it would be more air flow.
Your ECU isn't going to know what the fuck to think.
Intake manifold and throttle bodies will fit but you won’t be able to use the dual air boxes.
Probably won't work, the s650 uses two MAF sensors.
Advice on tuning and performance enhancements
Properly etuned.
Highest knock I've ever gotten has been -1.05 and that's rare.
General tips for regulating intake temperatures
I was wondering if anyone with longer experience has any suggestions on ways to help regulate a lower temp for the intake.
Discussion about OEM vs aftermarket intake options
I will not use a generic plastic intake manifold on this engine with the way they warp and crack and how the generic ones rob you of about 40 hp.
There isn't any good options for the 4.6 V8.
But if you’re looking for performance, look for a performance part.
the amount of headaches trying to just put my 4.6 V8 back to stock is becoming more and more hard.
General tips and links for finding OEM parts
Google the part # 9w7z9424a.
Apparently they have OEM ones for sale, about $466.
Discussion about aftermarket intake manifold preferences
Is anyone selling a genuine intake manifold?
haha you actually want the factory one with the plastic bits?
Maintenance considerations with intake upgrades
Maintenance isn’t going to change with 3 stage intake.
General tips for tuning and performance enhancements
Solid advice. Could even get rid of the resonator and cat for a louder ride.
Consideration of impacts from disassembly and reassembly
was it immediately after the tune?
Price increase due to OEM discontinuation
Well this explains why the price of them has more than doubled in the past 2 months…
They discontinued them about a year ago and third party sellers went out of stock fast.
Discussion about fair pricing for intake manifold services
I was expecting maybe $1000 but apparently not?
Sounds about right.
expect a little more.
make sure they use the new style gaskets they are metal and rubber instead of plastic and rubber.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Recent replacement experiences
Crazy I literally just replaced one of these yesterday 😅
Discussion about warranty coverage for intake manifold issues
Is this covered under that warranty? I notice the brochure say intake manifold run.
Yay! Sounds like the sensor position pin broke. If I'm right, it's sort of good news.
Discussion about aftermarket intake installations and potential issues
Guy had the car for a week and was already putting in an intake but needed the dealer to install the homelink mirror?
Discussion about aftermarket parts and their performance
The 2020 is the better driving experience because the transmission listens to the driver's inputs.
Discussion about detecting vacuum leaks
Soooo nice.
