AEM CAI takes in water
My 2001 LX 5 speed sedan with an AEM Cold Air Intake seems to injest water when driving through standing water on the highway, it seems as though the right front tire is spalshing water onto the air filter portion of the intake and then i'll hear a growling sound. I try to keep the rev's down to help keep the airflow through the intake to a minimum when driving in hard rain. It seems to me that I may have to rig up some sort of splash gaurd somewhere around the airfilter to try to prevent this from occuring. Otherwise I was also thinking about cutting the intake and installing the airfilter in the space left my the origenal equiment airbox, near the battery. I know that the air taken from this area won't be as cold as down low, but it may solve this serious problem of the engine injesting water.

Rep Power: 0 The growling sound would happen right after water splashes into the intake, usually from standing water on the road. Having the air on or off does not make any difference. Thanks!

Rep Power: 0 was curious becaue mine seems to make a similar noise but only when i have the air on defrosting the windows. im considering taking the bottom pipe off for the winter and just getting a filter that fits the top pipe, just to try it out. i dont think you will notice to much of a difference in engine prformance, but it will be safer.
ok kids... u gotta think about these things first before you attack them.... the noise is not your intake..... its the bottom skid gards... they collect water sometimes and makes this sound... I get it often when i rains also... and i have a AEM CAI...with no bypass.... i took it off cause it slowd it down.... but the sound seems like your tires started to rub right? its like a vrrrrrrrrrrrrrrrrrrrrrrrrrr sound ... its the pieces of carboard plastic that we have in our wheel wells and under the eng compartment.... u can cut them out.. but then ur engine is gonna get real dirty... best thing to do... is ignore it... or fasten the pastic /cardboard covers together tightly sealed...[IMG]i/expressions/laugh2.gif[/IMG]

Rep Power: 0 The growling sound is associated with a loss of power and the engine kind of sputtering a bit, so I really don't beleive its just water hitting the splash guard near the wheel well.
I was told that somebody makes a filter that's closed on one side, but i'm not sure who the manufacturer is. I'm going to try to fabricate some type of sheet metal shield extend the plastic splash gaurd and cover the bottom of the filter too.

Rep Power: 0 DO NOT GET THE BYPASS VALVE, AEM has had a recall on all bypass valves because they dont work. aem has had to replace sevveral enginge b/c the bypass vlave was sucking in dust destroying the engine. the best way to fix the water splashing from your tire is to put some kind of plastic piece net to the filter.

[hr]Voluntary Safety Repair/Replacement for AEM Air Bypass Valve
Advanced Engine Management, Inc. (AEM) and NHTSA Announce Voluntary Repair of Air Bypass Valve
[Los Angeles, CA] [Washington, D.C.] -- In voluntary cooperation with the National Highway Traffic Safety Administration (NHTSA), Advanced Engine Management, Inc. (AEM) of Hawthorne, California is voluntarily recalling about 3000 AEM Air Bypass Valves sold to consumers by independent distributors and retailers between August 2000 and January 31, 2001. Under certain circumstances, the Air Bypass Valve (constructed of 2 plastic pieces sonically welded together with a silicon diaphragm and foam spring on the inside) may come apart and, in certain cases, the diaphragm and/or foam spring may be ingested into the throttle body, sometimes forcing the throttle to stick in an open position. This may present a driving hazard to consumers who have installed the AEM Air Bypass Valve.
AEM has received three reports of the Air Bypass Valve coming apart. One of these reports described possible damage to the user's throttle body. Another of these reports described the diaphragm and/or foam spring being ingested into the throttle body, forcing the throttle to stick in an open position. The other of these reports described the valve coming apart with no resulting damage to the throttle body and no sticking of the throttle. No injuries have been reported.
The recalled Air Bypass Valves are identified by AEM part numbers 20-401, 20-402 or 20-403. The affected valves were sold to consumers only between August 2000 and January 31, 2001.
The subject valve is easily fixed, and AEM will provide all consumers of the AEM Air Bypass Valve with a free easy-to-install clip to prevent the diaphragm and/or foam spring from being ingested into the throttle body. However, consumers who have installed the subject Air Bypass Valves on their automobiles should not drive or operate their vehicles until either the Air Bypass Valve is immediately and entirely removed or the remedial clip is installed. The remedial action should take no longer than 5 minutes to complete.
The installation of the remedial clip is a simple procedure that will fully remedy the potential problem. While the remedial measure is not necessary for AEM Air Bypass Valves purchased after January 31, 2001, consumers with any concerns regarding these later-sold units may also obtain the free easy-to-install remedial clip.
Only those AEM Air Bypass Valves identified by AEM part numbers 20-401, 20-402 and 20-403 which were sold to consumers between August 2000 and January 31, 2001 are the subject of this recall. AEM Air Bypass Valves sold after January 31, 2001 are not affected, and consumers of AEM products bearing AEM part numbers other than 20-401, 20-402 and 20-403 need not be concerned.
AEM reminds its customers and consumers that the AEM Air Bypass Valve is designed and intended for use only with the AEM Cold Air Intake systems. Use of the AEM Air Bypass Valve in conjunction with any other system is neither recommended nor warranted and may result in, among other things, malfunction of the AEM Air Bypass Valve.
For further information, consumers should call AEM at

Rep Power: 0 In other words, get a bypass valve since by now all the ones that were sold between August 2000 and January 2001 have all been used/trashed/burned, etc. ... since that was well over a year ago and AEM fixed the problem
