None are a true CAI in most peoples state of minds. The AEM and K&N have more airflow from the air dam and heat box but it is still up top in the engine bay. There are no CAI in the sense of long piping down to the wheel well or directly behind the grill, and there won't be due to the lack of space in the 2.5 and especially the 3.5
All intakes will offer a similar gain in HP (a couple) and the sound differences are there but minimal
On the market there is AEM, K&N, Injen, Fujita, Weapon R. I think that's it but those are the main ones at least. All of this has been covered time and time again, it's mostly decided on your preference. I chose Injen because it looked nice and didn't break the bank. Along with them using blue filters now (matches my black and blue theme) I was decided from the get go
