BMW may have added improvements in the intake manifold, runners, secondary valves in runners, or ECU tune to remove the need for an intake resonator.

There's many reasons beyond what you can see on the outside.

Same Engine, Same HP and TQ numbers, built at the same time... only difference... one marketed as an upclass sports saloon (quiet) the other is a sports coupe, sedan or vert.

The link talks about performance, but this also ties into the primary reason: stock ECU tune for maximum balance of performance/reliability/emissions.

OE intakes are designed that way for a variety of reasons, many are related to actual driving comfort of occupants in the vehicle from what we can hear/tell. A lot of aftermarket exhausts have annoying sounds at specific frequencies because of lack of sound tuning for this reason.

Just because it's TRD doesn't mean it's Toyota's aftermarket gift to this car.

-alex
I think the only reason the FR-S has a resonator is because of the sound tube.
Be it a TRD intake or any other brand they don't have a resonator because these intakes delete the sound tube so there's no need for a resonator.

I can check with Toyota Corporate about this to make sure this is why the stock intake has a resonator.

Aside from sound, the chassis is different... so the platform and conditions under which the car is designed is different.

Also, I'm willing to bet the gearing and final drive, as well as suspension (wheel) specs all play a role in how the engine intake is tuned.

Splitting hairs here but the main thing is, it's not just as simple as sound to most of us.

Non of that has anything to do with a engine intake resonator, now you're just talking non-sense

WOW - you folks are informative and fun .....

@campy - thanks for the diagram idfentifying the part.

@mav1178 - thanks for the link with the information.

@dsrttigr - so that's where they keep the cricket feed (I fixed them up, by dusting some DDT into the intake).

@TRD-X - now, I didn't fall off the pumpkin wagon here in Puyallup .... I do know that the flux capacitor is part of the electrical system....cause the black box didn't shock me.

@BANGER - no..no..no ... cause it doesn't have a yellow cap.

@Luis_GT - are you bi-polar..??? (jest ah messen wich ya).

@djleepanda - are you from the south .... ??

Well, thanks all .......... :happy0180:

This seems to explain it pretty well:

From the reference:

"The Resonator
Adding an expansion chamber to the intake tube forces air coming back out of the engine to slow down to fill the cavity, thus expending a great deal[IMG]file:///C:/Users/Roger/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png[/IMG] of its energy and slowing the pressure wave reversion. This slowdown allows fresh air to flow toward the engine without fighting pressure reversion waves the entire way, thus aiding in cylinder filling. Since these pressure waves are essentially sound, giving them a place to expend their energy before exiting the air filter box ends up dampening the intake noise and quieting the engine. Thus, the resonator helps to make the engine paradoxically quieter and more powerful."

Thanks again.......

humfrz

PS - no one mentioned it might be a muffler bearing .... ??

They do, because again they're part of platform design goals. Yes it's just noise to you but that is one part of the unknown.

As for the other personal insults, keep them coming. It's entertaining to see what some people are like on here.

Right design goals other than suppress noise... keep thinking that... mean while, I just drop in the E46 intake tube and have glorious intake noise.


PS, a 330i Engine and transmission is plug and play with my 530i.

Yeah after seeing a bunch of his posts, all he wants to do is look superior to everyone. Everybody could appreciate a knowledgeable person, sure, but to always come off as a Mr. Know-it-All is really getting old.
