And saying you live in a rainy area so you didn't get a cai is like saying your roads are too shitty to be slammed, its just not an excuse. Anyone anywhere can have one. Hydrolocking is not the devil everyone makes it out to be. It doesn't happen from driving through a two inch puddle, otherwise i'd be hydrolocked. As long as you keep the splash shield on the bottom and get a prefilter you'll be fine.
thats not exactly correct... the valve doesnt expel water through it. if the normal filter because submerge the valve opens and it sucks in air from the bypass. When there is a vacuum in the intake, from the end of the intake being submerged in water, the bypass valve opens to suck in air...once the vacuum stops(i.e. no longer submerged), it will resume sucking in air from the regular filter. air will take the path of least resistance.


That being said, I've driven in plenty of heavy rain situations and have not hydro locked my FSWerks CAI. Just be smart, avoid puddles, ponds and lakes. The factory splash guard will keep most of the water out, just dont submerge the front end of your car. If you are really worried about it, then dont modify your car. A SRI or CAI with bypass will pretty much decrease your chances of hdydro lock all together though...
