i read about the lean issues previously.... but i had mine on since new (about 5 months) with no problems, and car still seems ultra rich from the looks of the exhaust tips. gonna get tuned pretty soon though.
also, i think if you do a search, some have reported raised boost levels... though i have no way of verifying except that my car runs well as is.
as for the "best" intake... there are only a couple that are CARB legal. and the AEM one appears to be the most well designed.

the exhaust tips aren't exactly a great way to measure AFR 
my car is tuned and still filthies up the tips and the back of the car pretty well.
if you get the AEM intake it's definitely better to tune for it. the good thing is you can find the ecuflash maf scalings online if you search, and Cobb AP has OTS tunes for it. of course, it would be better just to get a proper tune, since that's the best bang for your buck mod out there anyways

just waiting for the moon and stars to align so i can get down to the tuner.op--another consideration which may or may not be important to you is whether you like that blow-off sound. open intakes like ams' are MUCH louder. i heard my friend's ams unit and was really jealous. the aem is a bit louder than stock. but i feel the aem is still more engineered, so i kept it anyway, secretly wishing to be more ricey.

Measured at highway speed so that the airbox was getting nice cool air from the front of the vehicle vs. the cobb that was getting it from the engine bay. The cobb did not have a heat shield, so the AMS and other units that have a head shield would probably see improvements over the cobb as well. the temp was measured via the cobb AP (ecu).

hey st1g, i see that you have a 2010 evo x..just want to inform you, because you have the aem intake..i have a 2010 evo x too..i got the aem intake too..
when i installed the cbe and aem intake, my afr's where damn lean (like 11.9-12.3 yes 12.3) and unstable, and i was untuned at that time..so that's why i quickly bought my tuning tools..remember the 2010's had lean spool on + the aem intake increases boost due to the vacuum lines + it has increased maf housing..I'm not saying AEM is bad, it is well designed IMO due to the airbox..but you need to get that thing tuned..that is why i changed the intake pipe to nisei and use the stock maf housing to get more accurate readings in the maf..just trying to let you know.
