Jon sounds to me like he knows his stuff, but I agree that his knowledge sounds like it may come from a different platform. I already know Justin knows his stuff...his retention for things he learns amazes me considering how often he walks on the moon.

With his description it definitely doesn't seem that way to me either, sounds like he knows his stuff. Just doesn't apply to the design of the TL intake that's all haha

I thought the resonator box was only there to limit the noise? How exactly does it "speed" it up?

The result is a "clog" or high pressure area in your intake tube that ultimately limits airflow through almost the entire rpm spectrum.
this means, you can feed it as much air as you want, the throttle body will be the restriction and will limit how much air will enter.
with the 3.7 shawd manifold and its respected throttle body swap, we've stepped up to a 4 inch intake

Pretty sure I didn't ask you if it was bigger or not. I know it is.
What I'm getting at is what part of the slight increase in inner diameter makes you disregard your statement that the TB is the limiting factor and there's nothing extra you can do before air enters it. Is there an inverse relationship that would support that the motor is stifled without a jump to a 4" intake filter/tube now?
Maybe I misunderstood what you're trying to get across. Just cause you're smart doesn't make me dumb, spaceman.

However, any air tuning is done in the intake manifold and not before it.

At some point going bigger will yield no benefit, unless you get a bigger engine.

With the 3.7 shawd manifold and ZDX TB, do we still look for an air intake made for a 04-08 TL or some other model? I suppose it has to be for a TL, in order for it to have the correct bending and length, connections, etc.
Wish we had a list of all these parts and their diameters...3.7 mani, ZDX TB, stock parts, diff air intake system piping diameters such as injen, aem, etc.

it is in fact bigger, on the inlet and outlet.
I believe IHC has done an airflow test to see how much the stock intake and its air filter flows, and determined that the acura engineers did not leave any hp on the table.
meaning, the stock intake and filter outflows the stock throttle body at WOT.
this is why adding a cold air intake does not increase HP tenfold. at best a cold air intake increases hp marginally.
now, when we step up to the 3.7l shawd intake manifold and its respected throttle body, everything is bigger and of course more air is needed.
I was explaining the Helmholtz theory, but "I think" any tuning is done after the intake manifold and it would be best to feed it as much air as needed.

thus why we stepped up to a 4 inch intake and discontinued using the "aem" 3.25/3.5inch intake for the 3G TL.
we do have a very great thread started by I Love Cars, that details every single item, every single increase, every single detail that you could ever singly need.

if upgrading to the 3.7 manifold and 3.7 throttle body, OBVIOUSLY, you need more air.

Wait...is it a single thread?
Well, aside from being mildly butthurt when I responded...I appreciate your retort. What I was mainly trying to understand is why it would matter to feed more air to the 3.7...I doubt a factory 2012 TL SHAWD has a much bigger air tube into it's TB.
I feel like for all the money we spend on these engines and this that and the other bolt on, we see marginal results. Most of my modding is done because it's cool looking, sounding, or cheap enough to not mind giving it a shot.

and family guy, if stock throttle body is less than 76mm? lol because it is. I bored the stock throttle body out to like 78-80mm, I forgot.
and the 3.7 throttle body is at 78-80mm already.

So at 80-83mm the stock intake tube or even a traditional 3" CAI and filter become the limiting factor instead of the TB itself and a 4" intake is now necessary to keep the TB/Engine from suffocating?
It just seems to me that the logic is being applied to one application and then goes out the window with the use of a slightly larger TB.

stuff the most air you can at the throttle body
take everything i say with a grain of salt, as Im still on the 3.2 manifold. albeit, ported and polished with a bored throttle body with the stock intake sans resonator.

Celebrity Death Match?
ILX. But same thing when it comes to the intake and many other things.
And no subie either. Just tore the front lip off one and stuck it on my ILX.
Thanks. I talk a lot of shit but I try not to talk when I don't know. When we say walk on the moon am I catching the right vibes?
Though in this case I jumped to conclusions. I'll explain in a second.
I was talking about the TL. But honestly the intake is the same exact thing. Well the placement of the TB might be different. But its a similar box to probably the exact same resonator.
It does. But as I said I jump to a bit of a conclusion.
I didn't realize you guys where still using some sort of ducting to locate the airbox inlet away from the engine further. I literally though you guys had the airbox with an open hole on the bottom and that is all.
If you guys got some ducting, spectre sells some, you could relocate the intake tube directly to the bumper with something we had for our integras.
trololololol
It acts as the ducting toward the outside of bay. Yes it's main function is noise dampening but without it there isnt as direct of a connection from the intake to the outside air.
