On ebay you will be able to find a CAI Bypass valve/fliter thingy that doesn't look anything like the aem one...

the aem one DOES prevent water from being sucked in to your engine...some mag did a test on it, with a guy's nsx...

soo any one done a test with the ebay one???

------------------

if nobody owns one.. i might get one and test it.... not with my car of course...

i'll just hook it up to a wet vac... and see if any water gets sucked through...
