i'm not positive about your application, but you could also buy whats called a bypass valve. it's made by AEM and goes between your filter and the throttlebody. once it loses suction say if you were to actually suck up a substantial amount of water, the valve closes off the lower section of your intake and opens up breathers located around the radius of the valve. but daman is right unless you take in quite a bit of water you should be fine. we lost an srt-4 engine that way. took in a little more than 3 gallons of water through the intercooler and all. bent a rod.
