Well I have an AEM Air Bypass Valve and the box states that its only for AEM CAI systems only. Has anyone hooked up an AEM bypass valve into a non-AEM CAI system? Does it actually work with other CAI systems? Thoughts? Thanks.

 

I don't see any reason why it would only work with their CAI's.

 

If it's what I think you're talking about, that is simply for long tube CAI's where the filter may get submerged or potentially suck up water. This bypass is supposed to prevent water from getting sucked up into the system. So, there is nothing so unique about he AEM system that this would not work.
