i see what u mean..its not a SURE SAFE way...but it sure as heck lessens your chances by far.

I read it "shuts off" the air intake when it detects change in pressure or somethin? So basically ur engine will stall when it detects water?

imagine a straw. You are inhaling air into it and when u stick it into a cup of soda, wut happens? YOu start sucking the soda through the straw right? Now cut a hole in the straw and try to suck up the soda through a straw. Nothing comes up but you seem to keep on sucking up more air, right? That is the idea of a bypass valve. It lets the intake take in air from mid pipe so you don't end up sucking water into the engine causeing hella damage. So if ur intake is completely submerged, the bypass valve opens so ur engine will be able to breath insted of drown.

 

Looks like I am putting mine back on.

 

but....when it does that...is it breathing "unfiltered" air?

And does this work for tiny droplets of water that would come out of a soaked filter? I remember my filter was completely soaked. So i guess it sucked so hard it sucked the water through the filter and up the intake pipe into the injector chamber.

Now...the bypass should cut off before it try's to suck up water through filter fibers(which is hard to do). I'm just saying that if u get a splash on your filter somehow, ur engine basically starts inhaling unfiltered air from your engine bay. Personally i dont like that.

I know its a better alternative to hydrolock, but is there a way you can "re-route" it to another filter somehow? Hmmm...something like this doesnt require that much thought.

I guess you should just drive slow through puddle or avoid them completely!

the bypas valve is incased in a foam filter of its own, so the ait taken in is not unfiltered. The AEM BP valve is more like a second filter on ur intake system. copy this link and check it out. Probably if u see it, it will explain a lot more about it. http://www.import-performance-parts....pass-Valve.htm

 

hhmm...i looked at that link....and what i am trying ot figure out is how this works. Is the black stuff the filter? and the two holes are where the "pipe" is fitted onto? Where does this install anyway?

btw..thanx for the link..helped alot!

All you do is cut a CAI in half before the intake starts to bend down into the fender well, slip the Bypass valve btwn the 2 halfs and reinstall the CAI where it originally was. On the pic where you see the grey foam around the valve is where it breaths in the air if the intake is blocked or in water. The two big openings is where it fits on the intake.

 

ok...that's how i imagined it. But u have to CUT the intake pipe? Isnt that alluminum(or similar material)? So you need a pipe cutter for that. And do all CAI have the same size diameter piping?

thanks!

Dave

 

no, they can range anywhere from 2.5" to 3.5" in diameter. Most standard CAIs, especially for the accord is a 2.5" though. The pipping is alluminum so yeah, ur gonna have to cut it. Make sure you sand down the edges and clean out the inside of the pipping really good before you put the intake back in. Metal shavings and cylinders don't do too well with one another.
