I hydrolocked my motor going through a deep puddle that was about 2 feet deep a couple years ago. It was dark out, so I didn't really see the puddle or how deep it was. I had a Prodrive CAI on at the time. I still have it, and I sometimes think about putting it back on. Sometimes **** happens. I never thought I'd be dumb enough to drive through a puddle deep enough to do that.
