AEM lied to you with "10-15hp gains;" that's bullshit.
The only advantage the CAI has over the SRI is that it sucks in cold air. True, cooler air leads to a denser air mix, which translates to more oxygen for your car to burn. However, when your car is travelling at 20mph or above, the air that's flowing through your engine bay will keep the air as cool inside as it is outside. If you're really paranoid about warmer air with an SRI, get a Comptech Icebox or if you're on a budget make a DIY heat shield over the filter. Those two options are the best compromises for power.
People who tell you their CAI made their car faster are using their butt dyno. It's been proven that the CAI does very little in terms of performance compared to the SRI.
Finally for those people who still think their CAI is hella awesome, the hydrolocking tendencies of the CAI can be avoided with a bypass valve. Good call.
