your worried about the risk of a CAI, but in your sig you want boost. if your worried about hydrolock, you have way more to worry about with a turbo. there are way more variables involved with a turbo. proper fuel management, proper timing, throwing a cel code so you can pass inspection. there is more stuff that can go wrong with a turbo. a CAI is way more safe than a CAI. you have to be willing to take some risk if you want some performance out of your car. I've had my CAI for about 4 years without a problem. I drive with common sense and have never had an issue.

CAI=low risk=low hp gains
turbo=high risk=high hp gains
taking a risk+turbo=high hp gains

 

You have a good point, turbo has problem potential too, but I would just feel like a dumbass if I sucked water into the engine accidentally esp becuase the difference between CAI and a short intake is not that much. At least with turbo its a large performance gain, thats worth the risk to me.
