For people with aem cold intakes, is it necessary to install it?

 

I'm putting mine on like right now (CIA & valve) For $30, it's worth it I think to reduce the risk of the water intake...
Up to you though!

I think he means "CAI" not "CIA". Unless it rains like mad in your area, you won't need it.

in my opinion i wouldn't get it for two reasons: (1) it is probably restrictive and can reduce the performance gains of a cai (2)i heard there was a recall or something because it would get loose and get shot up into the throttle body.

 

Yes on the CAI not CIA!!! But I do live near Langley.
Anyway, looking at the piece, not sure how it would shoot up there.
Wish I could grab a free Dyno in the area, I'd be happy to post before/after w/ & w/o the bypass valve...oh well!

What is this about a recall on the bypass valve?

 

don't know exactly, but the little foam thing in OLD bypass valves would get sucked up the tube, and would plug the throttle body. On new models, it is not a problem.

 

This is from AEM's site.

Advanced Engine Management, Inc. (AEM) and NHTSA Announce Voluntary Repair of Air Bypass Valve

NHTSA Contact: Kelly Schuler
(202) 366-5227
AEM Contact: A.M. Rudy
(310) 484-2322 x500

[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 (310) 484-2322 x500 between 9:00 a.m. and 5:00 p.m. (PST) Monday through Friday.
