As I have never driven an S 2000 with a Mugen intake, I cannot comment on it one way or another. From the pics posted above, it looks similar to the "Spoon", but is undoubtedly more refined. The Mugen, Spoon, and the AUT that I know and love seem to work on the same principle of allowing air to be drawn from a point behind the grill, in front of the radiator, and out of the engine bay. And this is indeed a good principle!
Some other comercially available intakes, however, are not based on this principle. Instead, they are "CAI's in name only, and really intake hot air from the engine bay. Some of the older AEM's that mount a bare filter element low in the engine bay add hydrolock to the problems of hot air. As a test in briefly considering one of those, I mounted a cheap thermometer on a rod, placed where the bare filter would sit, and drove 1/2 mile. It hit 130 degrees and broke! CAI, my butt!
But the Mugen, Spoon, AUT, and the 2" pipe the OP has run from the fake bumper vent to the air box all provide a source of intake air that is not super heated by radiator or engine bay, and therefore they are true CAIs. But, of course, some of these cost more, and probably work better, than others. All are surely a step in the right direction.
Thanks,

The AUT Cooling plate dosn't "draw" air from anywhere...its suppose to "divert" air...and unlike the Spoon or Mugen there isn't any ram air effect. The Mugne and Spoon specifically draws the air from the front of the bumper, along with J's, ASM, and whatever intakes use the snorkle principle, but not the cooling plates.
Well, see my post on the previous page -- the one with a link on it -- to see how I added "ram air" to an AUT cooling plate and CAI. You'll see a "great big honkin' scoop" behind the grill compared with that on the Spoon. Without this scoop, the AUT CAI would be merely a "passive" source of cool air from in front of the radiator. With the scoop, ram air is present at speed.
V.S stands for velocity stack, which is the metal thing that comes with the mugen intake. It reduces pumping losses and helps to optimize intake velocity by straightening the airflow entering ur intake. It also propagates wave formation in the intake, making the intake work more effectively. It will provide greater throttle response and yield a bit more hp. For a V stack to work, the intake pipping size needs to be the same throught out, from the intake side to throttle body. the V stack would not work if u have sth like the j's, that's y mugen uses the stock intake arm.
Thanks for the info. I see what you mean by all the R&D and engineering that goes into the Mugen CAI. It doesn't just clip into the stock air box like the Spoon, does it?

nope...it's more like the J's where it replaces the stock airbox...with J's the cf chamber you see replaces the OEM intake arm...but both Mugen and J's replace the OEM airbox
Thanks, all. I think I see the benefits of the Mugen and J's intakes now. While my DIY rig using mods based on the AUT CAI and rad plate (link posted in my earlier post above) does supply a bit of cool "ram air" to the stock air box, the handling of the air after it reaches the air box is still stock. The Mugen and J's also improve the air handling efficiency post - filter.
I still like my mod better than a Spoon, which also retains the stock air box, because my mod has a larger air scoop. But it no doubt won't hold a candle to the Mugen and J's. Considering that my mod cost only about $250 (including the K&N filter), so it can't be expected to "run with those big boys."
I'm using the AUT plate now on my 06...can't beat it for the price...simple, elegant, feeds air to the airbox...I just removed my oem airguide so the air can get to the aut and called it a day...for now anyway
