Product Description
AEM’s 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.

Customer Reviews
Fragile to say the least
I purchased this product for my AEM Cold Air Intake system to
elmiminate the chance of hydrolock, a condition that occurs when your
engine ingests water, which cannot be compressed like air, causing
damage to your piston rods. Unfortunately my order arrived damaged,
with a small tear in the foam housing of the valve so I did not have a
chance to install it. I would like to give a few tips to check before
purchasing this product though. First off, this valve is large it is
about 2 times the size of your intake pipe and cannot touch anything
after it is installed, so make sure you have the clearance around the
pipe to ensure that it will fit. Secondly you will have to cut a
section of your intake pipe, or have someone else do it, either way you
probably don't want to purchase this if you are not comfortable with
making this modification. Although I had problems with my product I am
in no way suggesting that you will. The damage to mine was in shipping,
not bad manufacturing and I would like to recommend this as a worthy
addition to the Cold Air Intake System.
Good insurance for your engine.
Seems very well made like all AEM products, not the easiest install
because you need to remove the air intake and cut out a section to fit
the bypass valve. Make sure you install your CAI first to find the
right spot to fit this, also make sure to remove all the shavings good
from cutting the pipe if not all that crap goes in your engine and will
be detremental to the engine. I do not know if it works yet and hope I
don't need to test it but its good insurance just in case. I have mine
installed on an 03 Accord i4 w/ 2" drop and an AEM CAI, I installed the
valve on the pipe behind the battery, fits good, looks good.
