I am not saying one is better than the other. To be honost, you WILL NOT FEEL A DIFFERENCE BETWEEN SRI AND CAI
This topic has been done to death!!
What I WAS saying is that an AEM SRI is the exact same depth as the Injen CAI but the AEM is INSIDE THE ENGINE BAY, where the Injen CAI is in the wheel well.
And, if you were worried about sucking in water, don't get the AEM SRI, cause it sets at the bottom of the engine bay. See pics above
I don't mean or want to start a flame war of SRI vs CAI, but, in all honosty, the CAI piping goes the exact same place the SRI does, and if you're at speed, the engine bay temps are not that much different than a CAI intake in the fender.
