I know that AEM says that their bypass valve will only work with their CAI and not to use them on other CAI systems, but has anyone had any experience with them? Is it just a marketing ploy to get you to buy their expensive CAI, or are there actually reasons as to why they cannot be used on another CAI.

Thanks for the input.

 

Size of the piping.

 

So, if I have something the same size of their pipe, it should work?

 

don't see why it wouldn't.

 

anyone know what the ID/OD of the AEM pipe is?

 

hijacking your thread, sorry bro. i got the aem cai for my ride i also wanted to get the airbypass valve too , but in order for me to but it on i would have to cut the cai would this effect the flow of air going to the (tb)

 

i got the bypass valve installed on my cai, but i had the same question... the guys from my performance shop said it wouldnt, because the seal on the bypass valve is air tight

 

I would not get the bypass valve if I were you. I had one installed on my Type R and the inner foam part got sucked into my TB. For one you have to cut your intake tube to get it installed. Second they rob you of horsepower. And third you could end up just like me with a faulty valve that could cause some major damage.

 

THeir was a recall for this faulty BPV, the new ones are fixed. THey do rob you 1-2 HP. AEM uses differnt size pipe, which is why there are many different BPVs. I'm sure one would fit.

 

I have an AEM bypass valve for my aem cai and here is what I have found out:
1. Put it in to protect it from water getting inside (this is why I bought it right?)
2. Then I found out the foam will eventually break up and end up in the throttle body.
3. Does decrease a little hp.
4. That you really don't need it unless you try to drive through a pond, in other words rain will not harm you-especially if you still have the splashguard underneath.
5. In the winter, instead of putting that bypass valve on, just take your second pipe or tube off and throw your filter on the end of the first. (This is what I am going to do)
I still have it and am probably going to sell it because I don't need it. If I lived in Seattle, Maine, rain states, then I would probably have it on just in case. But here in KS, it's not neccesary for me.

I am sure that it would work on any intake piping as long as you have the same diamater as the bypass valve. Check out www.aempower.com and you can get to a chart with the bypass valve needed for the size of piping and model of car. Later.
