Here are two threads that will help.
Thread 1
Thread 2
anything else is just adding to the junk
here is some more UNBIASED information
Q-Have you thought about protection from water? That looks like it will suck it
up...looks like it needs the AEM valve and I think they are like $40-$50
A-An AEM ABV is an option for any Cold Air intake system out there. It is also
recommended but isnt necessary. I as well as many other Cold Air Intake owners
do not have a problem with water. Unless you plan ondriving through 2 feet of
water dont worry about the AEM bypass valve. The filter has to be fully
submerged to suck up any water.
The only thing is , your intake filter may become dirtier quicker.
Q- What is waterloc or hydrolock?! Why does it hurt my engine if my filter gets
submerged?
A-Hydrolock is when water is attempted to be compressed ... water CAN NOT BE
COMPRESSED and the engine seizes because the pistons basically hit a wall.
Damage could be as severe as broken/bent rods, broken/bent wrist pins,
broken/warped rings, cracked cylinder heads, cracked/broken crank rod journals,
broken bearings, ect.
However, to get to that, water would literally need to be sucked into the
intake. To accomplish this, the filter would need to be submerged in water. A
general misting around the filter will not cause hydrolock. If you have to
forge a stream or river, you are driving the wrong vehicle
Q-Would there be any performance difference between the type of filter used?
A-The filter does and has been shown to make a difference. The best out there
to use is typically a true K&N Filter. To keep costs low most sellers provide a K&N
STYLE filter. A true K&N filter as well as a heat shield can be purcashed online or can be found at
your local AutoZone.
