Hey, I've had both installed in my car. The AEM CAI
first, then the Injen CAI
. They are both GREAT Intake
systems, you can't go wrong with either. There's a little difference in noise. IMO, the AEM
was a bit louder overall, but the Injen
screams too once you hit the higher RPMs.
Power wise, this can be debated all day. But when you get down to it, they are both great Intake
systems and like someone said above, AEM
has better low end gains and the Injen
has a better high end. Just depends what you want. You can't go wrong with either, though.
