Ive asked over 3 auto shops that work with aftermarket parts and they all told me it doesnt work or dont really understand how it stops hydro lock. How does this crap work? and Does a By-Pass Value Really Work???

 

A bypass valve goes between the throttle body and air filter. Its basically a wire frame covered with a foam material. If they car were to suck up water, it would bleed out through the foam.

 

If your intake filter is ever submersed enough to take in water, the intake will redirect the the air flow from the by-pass valve, due to the lack of air flow from the submersed intake filter.......I have been wanting to get one for the longest time on my AEM, but always find something else to buy! LOL, I hope that this clarifies what it does for you

 

Ive heard you can lose some hp from adding this. Presonally unless you get floods I wouldn't waste your money.

 

not worth it unless u drive through some deep water.

 

i had mine on for a while then took it off & it seem better but could be in my mind but if the water is that deep you need to go a different

 

do they work? they probably do. but is it worth it? that's another question.

you really DO NOT need a bypass valve unless you're driving in knee high water. under most driving conditions, you will not need it. just use common sense when you're driving in hard rain; don't drive in puddles and go easy on the pedal so your filter does not suck as hard.

 

they work, as TOPHER33884 described that how it works, brother had it on his car for about 2 years and never was in deep water, and it could rain hard in chicago like the past summer. u could save your self a few buck and go one or two streets over and not get into any water. and it kinda looks out of place in the engine bay.
