very nice review stillen owes you one, because they might have just gained another cutomer 
But I wanted to clear up, the before numbers on the dyno are when you only have HFC's exhaust and jwt? If so, then what is stock to the wheel? Also, what kind of dyno is it? DYNO DYNAMICS, or DYNO JET, etc.
Thanks in advance...

I must say that this is the best intake for the G37 so far and the Magden computer showed why. It irritates me now know what I saw with the Stillen intake which you didn't see with the JWT or the Stock. I had to go back over the log data for the stock intake to confirm that this didn't happen on that intake or the JWT (still need to look at the JWT logs). What I am getting at here is the Intake Air Temp. I ran some decent numbers with the JWT at a temp of 36 Celsius and some good numbers with the stock at 30 Celsius. When the stock intake got up to 32 C is lost power and I would imagine the intake would get a little bit hotter. The Stillen CAI ran in the 28 to 29 C temp. Now you have to understand that when we got up to the 5th run and higher the Stillen intake was sitting at 34 to 36 C when we started the runs but at soon as we started the run the intake air temp would drop like a rock to 28 or 29 C in a matter of a couple seconds or less. This didn't happen with the stock intake. It stayed consistent with the temp it was at when the run started. It would maybe drop 1 C. Now before the Stillen I was mainly looking at this section just to verify how hot the intakes were getting and I was pleasantly surprised to see the temp drop like that with the Stillen. The placement of the sensors must be part of this equation.
Any idea how painful this would be to install if you didn't remove the front bumper? I'm not removing the bumper for an intake install, sorry.
Thorough review, looking forward to the JWT one.

How easy is it to get to the filters, for cleaning?
And not to be an ***, but are we looking at the same dyno's? Am I missing something?
Sure, the peak is 11 HP, but throughout the power band, the gains are minimal or you actually lose power. ONLY from 6500-7100 rpm, the gains look to be around 5 HP, and from 7100-7400 rpm the gains are more like 10 HP. But that's it for any real gains.
So all this incredible acceleration I keep hearing about is just in the upper 500 rpm of the powerband, and that's pushing people into their seat?
"Didn't have to downshift once to pass anyone due to the additional kick"
You didn't have to downshift, so you're cruising at, what... 3500rpm? I'm glad those extra 2 HP really helped out...
C'mon.
I'm not being a hater; I'm being realistic. I'm not saying it's a bad product, and I think you'll see bigger gains after a tune. I think the G37 ECU does not respond as well to simple bolt-ons (is more controlling/limiting), and a tune is even more important then ever.
