You reckon... I am trying to hear the moo sound again today. I could not hear it as easy.
One thing I did not use from Odula is the big bolts on the tube. I have smaller ones from the person that install it for me. Could it made the difference?

This thread is old, but I decided to go with the Odula Ram duct as oppose to the AEM/Mazda speed CAI or RB duct. I did not want to block my radiator or ATF cooler in anyway and like using the stock box. Just in case anybody was curious, the Odula duct opening clears the side of the license plate (Japanese and U.S. type), so it's not being blocked.
I didn't hear a "Moo" sound like it was described, but it might be the way he is describing it or difference in language.
The Odula duct does appear to improve performance (according to the butt dyno), will do some tests with a g-timer later. There is a slightly more aggressive "rrrrrr" sound, that is slight and I think the opinion of it would be subjective.
The Odula duct works well. In fact, I think Mazda should have designed such a duct in the first place. I suppose you can debate about the price and there is room for somebody to design a cheaper "copy cat/knock off" of this duct, but it does the job.
Now which is the better combo, RB duct with stock box or RB duct with RB box, Odula ram duct, AEM/Mazdaspeed CAI, etc... is another debate.

You can try Japanparts if your in the U.S. and looking for the Odula ram duct. Possible contact would be Graham Ware, gware@japanparts.com .
I'm not associated with Odula or Japanparts in any way, but I will vouch for the fact that the Odual Ram duct works very well (and with the stock box).

I'm assuming to fit either the pictured above, or the other odula duct, the vfad will have to be removed or modified. If not, then it might be a great alternative to the rb duct/stock airbox combo. I don't really want to cut up my vfad.

I understand that, but I'm a big fan of not being hasseled by the dealer. They are touchy about anything in the intake food chain and I think they would give me a rough time over cutting up the vfad for the RB duct. If the odula seals tightly with the vfad completely removed, or completely intact not neccesitating modification or a connector, I think that would be easy to return to dead stock and would ruffle the feathers of the dealer less.

The original odula air duct works well with the front license plate and its a bit to the side of it. Its the one that I have. You are definitely getting cooler air, as a result of this design. Odula has an comparison of the "cool air" effect at their website (also here). You may need/use google to translate the web page from Japanese.
The version 2 odula duct would be partially blocked by a front license plate. If you can take your front license plate off, will take it off when racing, or have a front license plate that tilts downward (they sell such license plate tilting frame kits in Japan) than version 2 might be an option.
However, how much air flow would be blocked by a front license plate using the odula version 2 duct would be somewhat up to debate. Because the version 2 air duct's inlet is wider than the original version its not clear how the inflow of air would compare (between the original and version 2), even though the version 2 duct is partially blocked by a front license plate. That all means I can't say if the original odula duct would 100% be better than the odula version 2 duct with a front license plate. You might have to try to get an answer from odula or setup a test between 2 people that have different odula air ducts.
Both air ducts fit with the stock box, which is another plus for them. And I can say that the original air duct works well. Its obvious that the version 2 duct would work well with no front license plate.
What might have been better for the odula version 2 air duct would be if it was slightly offset to the side and avoided interference from the front license plate.
An improved design would make the intake hole bigger (like version 2) and offset the inlet opening to the side to avoid the front license plate (like the original). The original odula air duct "triangle" inlet design might be better for this, but one side of the triangle might be straight and the other side have a wider angle. And/or you would design the tube to the stock box to angle to the left more so the inlet opening can avoid the front license plate.
Maybe Charles and his new auto shop at Paradox (hint), may want to consider this along with his new radiator design, or whoever wants to make a different design and new product.
But until then, I think the original odula air duct is worth it and much better (and cooler) than stock.
