Well I'm goin to lower my car bout 2 inches with BG coilovers next month and plan on gettin a CAI shortly after that. The bypass valve will determine whether or not i get an Injen or an AEM intake because I don't want to retro fit the Injen intake. So if I decide to get a bypass valve I'll get the AEM so it will fit right. But still, half of the people say no bypass valve and the other say bypass valve. I'm thinking of not gettin a bypass valve becuase alot of people say they mess up or deteriorate after a few years and I plan on having mine a while. So if i'm careful I think I can manage with the Injen intake with my car lowered 2 inches right? and drive really slow in heavy rain?
I need TP for my bunghole

Rep Power: 278 OK so we all know it works when the filter is submerged. It creates a vacuum & causes the bypass to open. BUT how often are you gonna be driving & have the filter completly submerged? The truth is more often than not it is water splashing the filter, and because there is not water all around there is not enough vacuum created to open the bypass. So your filter gets splashed you suck in water vapor & still get hydrolock. So if you wanna buy it for "piece of mind" go ahead BUT dont expect that just because you have it you WILL NOT get hydrolocked. You still have to be sensible & not drive too much in heavy rain & avoid large puddles. Just like someone else said the article is very one sided for it & does not represent what normaly happens in the real world.

Rep Power: 0 i think the bypass valve pretty much works, but with it installed, it defeats the purpose of an intake... cuz it sets up a barrier for the MASSIVE, CRAZY, amount of air that will not be coming into ur engine, correct me im wrong!

Rep Power: 811 Ya but who's gonna waste an engine for that? I've seen a video already, but they quickly submerge the whole filter in an aquarium before anything happens.

Rep Power: 278 There is a lot of diffrence between a lot of water & a little. Think of it like this, you drill a 1/8" hole in the hose of a vacuum cleaner (thats your bypass). With that hole it will still have enough pressure to suck up small particles (small droplets & water vapor) through the main end (filter) and there is relativly no suction through the small hole (bypass). Now take you hand and cover the end of the hose completly (submerging the filter completly) and you have a whole lot of suction through the small hole (bypass). So with out a WHOLE LOT of outside pressure on the entire filter you will not create enough vaccum to open the bypass.
