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 (310) 484-2322 x500 between 9:00 a.m. and 5:00 p.m. (PST)
Monday through Friday or visit the AEM website at http://www.aempower.com.

People laughed at us people getting Xephyr CAIs because we had to wait a long time to get the CAI.

Now you guys have a safety recall.

Now who's laughing?

Too bad I don't think the recall applies to you guys though...oh well that busted my bubble.

Each AEM CAI does not come with Bypass valave. So, they are NOT affected.

However, Each Xephyr Intake has the Bypass valve and each is affected by the recall.

If the batch AEM Valves bought by the Xephyr are recalled. He would be better post pics and send the fix ASAP to customer.

I just emailed chris regarding this, hopefully he didnt start stocking his bypass valves before Jan 31st... let's wait to see what he says. I ordered mine yesterday, I'm not concerned unless his stock was purchased b4 that date.

Let me get this straight: I'm supposed to buy this $50 device, designed to prevent water from being sucked into the intake and causing damage to the engine, and the device is faulty and sucks part of itself into the engine and causes damage, and uhm....er....uh...ahh...well, no thank you.

****** ALL XEPHYR SYSTMS HAVE BYPASS VALVES PURCHASED FROM AEM AFTER approx. 1/15/01*******

No need for concern

Also the CL-S has the VSA which would help catch the foam if it did happen to break free . The VSA butterfly valve "should" act as a buffer and make your ! light go crazy if it did happen. But as per the bulletin all bypass valves purchased (Ordered from AEM directly were AFTER the date specified) by a minimum on 1 month. Rest at ease all

Iridium,
Call me a dumbass, but doesn't the Xephyr also use the AEM bypass valve??

I guess this explains the Integra that I believe Jens talked about before that had the bypass sucked into the throttle body and stuck the throttle open at 3/4 or something like that.

Okay, dumbass. jK

Yeah Xephyr uses the AEM bypass but look at Xephyr's followup post.

Anyways the recall doesn't apply to the current AEM CAI anyways I stated that in my post.

I'm wondering the same thing here -- did we miss something? Jan 15th falls within the recall-date, how is that a GOOD thing for us?

Those of you who have it already, can you take a look at your part # and see if it falls within the recall list?

Yes it does fall in the part number that is listed above. If you have the CAI designed for the CL-S then your bypass should be part# 20-403. If you have the one made for the accord 98-00 then your part# should be 20-402.

Ok, maybe I am missing the obvious here, buuuuuuuuuuuut ..

if the part number is one that is being recalled, why are we being told to "not worry" ?

Crippen,

The part numbers listed encompass all valves made. The actual valves themselves have no distinguishing serial numbers that identify them. The dates are the only distinguishing factors - I will pull invoices and verify the dates to put this issue to bed.

Cool, thanx.

Mine hasn't arrive yet, so I'll hold off installation if they fall within the compromised range.
