AEM Intake Dyno'd with RRE!
Mike from Road Race Engineering isnt here to BS stuff. He's a great stand-up guy! If it's worthy he'll let you know, if it's crap, he'll help you look for something better for you...
I believe the results because of how rich the car runs and also being a true cold air intake instead of pulling the hot air from the engine that car be over 175-200 degrees to the ambient air from outside...

Nice work Mike and RRE, the results and net gains are completely realistic. Like others have said, I'm sure that some of the gains are from leaner AF and slightly bumped timing due to lower airflow readings. Either way it's still a great compliment to other basic bolt on mods and the design looks solid. If someone hasn't gotten a tune yet the 30 WHP gains are certainly real!
Once an ECU tune is done the gains will likely be in the 10-20 WHP range before and after but that is still good. Basically you are getting better spoolup and feeding the engine cooler air and still being slightly less restrictive then the stock airbox. I was actually planning on building my own cold air box with a similar feed from the stock location and also trying to get another 4" flexible duct to dump more air in there as well for the summer months. Worked great for my Evo 8 so the X shouldn't be much different.
I just found out my AMS intake shipped so I'll post pictures once I get mine all done.

I'm not surprised by the gain at all, if you look at the afr plot, it is very clear that AME is doing the same thing that every other intake manufacturer is doing, they are altering the amount of air "seen" by the maf sensor which put the car in a lower load cell and therefor results in less fuel and more timing. Plain and simple.
My only point would be that a tune accomplishes the same thing, so if you plan on getting a tune, not much point in spending a buch of money on an aftermarket intake that leans out the air fuels. If you don't plan on getting a tune, go for it, but do keep an eye on your fuel trims. Based on the published gains I would expect to see about +13% fuel trim on the test vehicle.
Now if it can be shown that AFTER tuning you still get a gain (though I suspect a much smaller one, like 10whp max) then I would consider it money well spent.
Good work and thanks for posting up the data!

Umm, no. The intake makes power on a stock car because it leans out the rich air/fuel mixture of the stock ecu programming. Once the air fuel is properly dialed in with a reflash, this intake will make no more power than a stock airbox because it isn't going to lean things out anymore. That kind of logic is like saying that if a piggyback nets about 50 hp, and a reflash nets about 50 hp, that if you get a reflash and then put a piggyback on top of it that you'll make 100.
Sorry, it doesn't work that way. As far as flow restriction is concerned, there have been many tests showing that the stock airbox with just a simple drop in filter doesn't pose any restriction at all until HUGE power is being made. Intakes are a complete waste of money unless you plan on keeping the car completely stock and don't do any ecu tuning. Drop in filter w/stock box FTW.
