With that said, both Matt and I are using a 4" opening on the top of the airbox. Both feed directly into the cowl. Looking at the Gruppe M access to the cowl, it looks smaller.

Also, both our airbox covers have been enlarged, Matt's considerably so in the front. We both use Amsoil cone filters, which btw, is an advantage. The Amsoil filter not only is much larger than that on the Gruppe M, but it flows better and is a dry type of filter.

Mine also uses an M&M scoop which feeds into the motor much more air than the little hole on the side of the Gruppe M. Finally, as was mentioned, I have a Soxfan143 MAF housing. Together as a package, I feel I am outlflowing the Gruppe M although I have no hard data to support that.

One airbox you don't need to be a rocket scientist to see the clear advantage is Moose's. Look how huge the airbox itself is. The cone filter is practically lost in all that space. Moose has a well though out side mount duct and has a ram air feed from the front grille to the airbox base. C'mon, no way the Gruppe M is going to top that.

BTW Mike, why did they include that lame front mounted scoop that attaches to the top of the cowl if their engineering is so much better than conventional wisdom?

So, with the larger airbox cover, 4" cowl duct, larger cone filter and Soxfan143 housing, advantage: backyard over Gruppe M.

Bill I'm not going to deny the fact that your intake flows awesome and it probably works awesome. Especially with my MAF housing. Hehe. Lol...but I should have mentioned that I was thinking of the Gruppe-M with my MAF housing on it. And the fact that this intake was designed on a motor without a MAF sensor really doesn't make one lick of difference. The sole purpose of an intake system is to get air into the motor. It does the same job whether it's flowing through and over a MAF sensor or not. As long as the air flows across the MAF sensor as designed and into the motor it will function perfectly. Also the motors are basically the same and that wouldn't make any difference either.

Second. I'm sure a company like Gruppe-M has a reason why that scoop is the way it is. They probably tested that thing in a wind tunnel and with all kinds of different scenarios and found that it worked better that way. I guarantee they do not make products with any gimmicks involved. I'm sure that a select few custom intakes will outflow it but the majority of them would not. And you have to compare apples to apples here. The Gruppe-M is a compact/show quality intake that functions extremely well. It's not some custom made 100% function only intake. In other words, they have to worry about appearance a LOT more than someone looking to up the performance only without bling in mind. So you have to give them credit for making something so pretty and so functional. I really should have explained myself a little more clearly I guess. But for just pure functionality and performance I would have to give it to you and moose.
