It's nothing but an over-sized paper weight. Dave Hughes is a bamboozler, he has no hard data to back his claims. A dual plane intake such as the Edelbrock Air Gap are designed to help bottom end and mid-range power on carbureted engines and do nothing for direct port injected engines like the 5.9 Dakota engine.

I have a lot of experience with Hughes an am currently using
this air gap kit along with some other products. I can't speak for
anyone else, as it appears some people have had bad
experiences working with Hughes, but I have had nothing but
quality products and services from them. Their prices are higher
than a lot of shops, but you do pay for quality.
Anyways, the intake manifold has been great for me. Not only is
there an increase in power across the entire rpm band, but I also
have noticed some better gas mileage. The Magnum engines are
not "direct port injection" as Kota360 said. Direct port injection
sprays the fuel directly into the chamber like in some new VW or
Pontiac engines. What I think he meant is that we do have true
multi port injection (one injector for each cylinder behind the
intake valve) as opposed to throttle body injection (an injector in
the throttle body that feeds all cylinders). It is true that when
using fuel injection the difference between a single plane and
dual plane becomes more manageable than with a carb and
some of the disadvantages of moving to a single plane can be
offset. However, your specific application will dictate what
manifold will be best for you.
I have used both the AirGap and the M1. The Edelbrock AirGap
design is an excellent compromise between single and dual
plane. It has larger runners which allow much more flow than
the stock keg style intake. It also supports higher rpm better
than many dual plane intakes. The M1 single plane MPI manifold
has huge runners in comparison to the AirGap. When using a
big cam, especially in stroker motors, you can see an increase in
HP and torque by using the M1. However, in most applications I
have seen the AirGap will provide the best overall performance.
You have to think of the heads, cam, and intake as one unit that
must be designed to work together. The intake runners are
essentially an extension of the cylinder head port and must be
tuned to do the same thing.
I have built a number of engines, and have used the AirGap with
some Fords and Chevys with success. However, the MPI AirGap
is slightly different since it doesn't use a carb. My experience
with the MPI AirGap was on a '97 dakota with a 318. I had run
the stock engine with the keg, then the M1 MPI, and finally the
AirGap MPI. All other things being equal, the AirGap was the
best for power and mileage. The M1 was fun up top, but it did
hurt low end torque (it is a GIANT intake for a stock 318). I then
rebuilt the motor with R/T heads, 1/7 rockers, and kept the
stock cam. The bottom end got new hypereutectic pistons,
otherwise it was built to stock specs with new hardware. I have
used only the AirGap since the rebuild and there is a huge
improvement over stock. I know there is more potential in it
and plan to upgrade the cam at some point in the future.
What intake works best for you will ultimately depend on what
your current setup is and where you want to take your engine in
the future. What is your vision for your truck and what are your
current mods? If you are looking to tear things up on the street,
you can't go wrong with the AirGap. People will argue all day
long about intake manifolds and what is better, but one thing is
certain: the AirGap is far superior to the stock manifold and you
wont find a better MPI manifold for the price.

I stand by my claims about Dave Hughes and Hughes Engines from one on one personal experience. You can talk all you want about how great it the Air Gap intake is, but until you can post hard numbers(ie dyno results), then it's just your word. Yes, I miscalled the injection system on the Dakota engine, as I should have said "Multi-Port". I would like to know how you have built Chevy and Ford engines using the Air Gap intake with a fuel injection set-up, as there is none available. If you did these builds on carburated engines, then your claims of big improvements would be correct.
I don't understand your claim of not being able to find a better intake for the price, as Hughes intake is more expensive than the M-1 from Mopar.
At the end of the day, if you like being lied to, and paying high prices for shoddy work, that is your own prerogative.

Yes, I did say that the AirGap I used on other brands was for a carb. The length and volume of the intake runners is whats most important, not carb or efi. I don't have any dyno numbers personally, since I don't have the time or money just to experiment with it. But I have built enough engines to know that the AirGap is a good manifold for many stock and mildly modified engines. The M1 may be cheaper, but it depends on your application. I would only suggest it for big cubic inch or high rpm applications. It is more suited for the track since it is good for high rpm horsepower while the AirGap is good for the street because it supports low rpm torque and can still flow enough at high rpm without killing horsepower. Yes, at a certain point the M1 will be a better manifold for your application, but it will depend on your specific motor and goals for it. Keep in mind that you can find both the AirGap and M1 used for a great price. Since intakes are one solid piece they are usually safe to get used.
It sucks that you had a bad experience with Hughes. Like I said, I've had nothing but good luck with them, but I can't speak for everybody.
I'm not going to have any dyno data soon, but I will have time slips from the track. I built that 318 with a stock cam so that I can have a baseline comparison for a handful of aftermarket cams that I'm going to try. We'll see what we can really make the R/T heads and AirGap intake do!

word to the wise, the huges if air gap intake does work, i have used mine for about a year, it works great, i have better low end power and upper rpm power too, i also have been useing the M1 2BBL for about 3 years prior to the fi airgap, it is a dog on low end, it IS designed for high rpm drag race use only with a really big cam, also i have never got any bad tech from huges engines, they do have dyno numbers for the air gap, you have to look thru their tech articles to find it, it's in there just look for it, also people need to quit bad mouthing hughes engines, they are the pros, you are not a pro, also every time when i call mopar performance up they refer me to hughes engines. so if mom mopar sends me to them then they do know what they are saying and doing.

I installed my fi airgap, machined tb and aem cold air today.
Massive difference. Great pull through the entire power band
and I only gained low end not lost. I am 100 percent satisfied
with Hughes customer service and product quality.
