Fujita Cold Air Intake
 

I just got this installed for my Mazdaspeed6, and this thing sounds freaking awesome. The only thing that I am worried about is water. Not that I am gonna go wading around in puddles or anything, but I remember when I had my Honda H22 accord, AEM had the air bypass valves.

I didn't see one made for this CAI neither did I see one on the AEM. Do our cars need them?

you can't run an intake bypass on a turbocharged car. Just stay away from the puddles.

I have driven with a cold air intake in all types of weather, snow, hard rain etc.--- I just stay away from the real deep puddles. Just don't go revving your engine through 2 feet of water and you will be fine.
