I have a cold air intake system and everytime it rains I take it aloose so I don't suck up any water through my intake system but I know that they have the aem bypass out and I'm wondering if it really works?

 

I have the bypass and have never had a problem with sucking water into my intake. I lived in DC where it rains 24/7, and now in LA where the drainage sucks. I don't really gun it through puddles either, I think you will be safe just not accelerating when going through big puddles. I always let off the gas, even though I have the bypass installed - I don't really want to test it out.

Some people on here and other sites will say that it actually robs you of 1-2 horsepower, but you know, it's an intake, so sometimes its better safe than sorry. I wouldn't go out and buy it if I had to do over, I would just get a short ram instead, most dynos have shown that short rams have similar or better hp and tq gains than the AEM cold air.

 

if you think about the whole idea of the bypass it seems like it would work perfectly. Where would the air be sucked in from? from the easiest accessible spot. Therefore if the filter has water on it or it somehow got submerged then it'll take the air from the bypass since it'll be easier to get it from there.

 

i have it and i hope not to test it but for $50 u should just get it and not risk throwing a rod through ur block

 

honestly imo the bypass valve is a waste. It is just gonna cause you to lose power and totally defeat the purpose of having a cold air intake. If you are worried about hydrolocking just get a short ram.
