Product Description
3.0" Air Bypass Valve Air Bypass Valve
General: Air Bypass Valve -

AEMas patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event the filter of your AEM Cold Air induction system becomes submerged in water. On most systems, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in. Check with your dealer or call AEM for more information on air bypass valve installation locations. The AEM Air Bypass Valve is C.A.R.B. exempt on AEM Cold Air induction systems only and is NOT for use on forced induction vehicles. Patent #6,394,128.

4 out of 5 stars It's pretty good...   June 1, 2007
Matt (Twin Cities, MN)
Being that this is an AEM product I expected a lot. I've driven through rain with this valve and have had no problems, of course if there were to be problems I would no longer have an engine due to hydro-lock, which is why this valve is so important if you want to run a Cold Air system ALL of the time instead of switching to short ram when it rains. It really is meant for just AEM intakes which is something you should consider if you bought an intake off eBay. Anything is adaptable, but it won't fit as well as if you would have bought a straight up AEM pipe. Overall it's a great product and works quite well. I would have designed it a little better, but whatever. The pre-filter is right out in the open and gets cut up sometimes. For the price, it's quite good.
