i was just wondering if anyone knows how the bypass valve in a CAI works?
Are they worth it to buy one? I live in colorado so it's somewhat wet here.

 

Without bypass (extreme circumstance):

Drive car.
Car on road.
Car hit deep puddle.
Filter get soaked.
Water go into engine.
Hydrolock.

With Bypass Valve:

Drive car.
Car on road.
Car hit deep puddle.
Filter get soaked.
Water no go in engine.
Bypass valve draws in air, not filter.
Drive car.
Laugh at puddle.

 

yeah i know what they do, but i want to know how they work.

 

When/If you drive your car on a deep pudle the filter gets clogged with water then there is no air going through the filter and that's when the bypass valve come into play, it sucks air in to keep the filter from sucking in water. Hope you understood.

 

It's kinda like a second filter for the CAI. If the first one, the one closest to the ground, gets soaked, then the bypass valve "becomes" the new filter. It just has these flaps on the inside that open up if the main filter isn't doing it's job because it's soaked.

 

ohhhhh ok, i got it, thanks a lot.
