i'm wondering if anyone has it. i just got a hotshot cold air intake and i'm thinking about throwing a bypass valve on it for safety. judging by the size, i'd imagine it's going to screw up my mounting points won't it? i was going to put it at the meet of both pipes so i could just use it as a cai all the time you know?

if no one has, i guess i could do this and let you know how it goes (aem will hear from me if this thing screws up my engine).

Wouldn't it fit between the Airflow meter and the CAI tube? I'm just guessing since I don't own a HS CAI

I haven't heard of any SE-R owners using it. But according to SCC it definately works. Go for it and let us know.

I don't know how true it is but I heard even the 3" Bypass Valve is too small for the Place CAi. It is a tight fit that will likely break the plastic part of the bypass valve. I have seen one but never touched one. This is what I have heard from people who have tried it with a Place racing Intake. The O.D of the Place racing tubes is slightly larger than the AEM 3" bypass valve.
Like I said, this is not first hand knoweledge, just what I was told by someone locally.

well they are only 45 bucks usually, so i'll order one up. i have the intake, but since my se-r is totaled i don't have a car to throw it on, so that gives me more time. i'll find one and put it on, and let you all know.

i'll leave your friend's honda alone, but obviously he hasn't read crap about the valve. they aren't supposed to lose any power, and how he can noticably feel a restriction on such a little part is a little wierd. however, i'll take it into consideration.

AEM is making a CAI for the Se-r and all other sr20 cars (it's true, it's true). As a matter of fact I think it's out by now. So definatly the bypass vavle will work/fit on this one.

unless there's a lot of gain id stick with pr's, or HS's. It took ten years for AEM to make a CAI for us. F them, my friends civic has an AEM. I dont want buttercup to resemble a honduh in any way.

Well I think I might give them a try (on my fathers NX2000). If no one buys the products that's out for our cars then they won't make (and sell) them anymore. "Were one goes, others will follow."

pretty sure that the bypass valve come with the rubber couplings (for 45 bucks it better). right now i'm shopping around hoping to find a place that has a sale on them (not happening) so anyone that knows of a place i'd really like the link.

of course, this could take a while as i'm still shopping for a se-r and battling with the other person to get what my cars worth money wise right now (these things suck!).

Can you just use a 3" rubber coupling to hold the two pieces together?

I have the AEM valve. I have not installed it though yet. It does not come with couplers of any kind. It slips on the CAI piping. It does not look like it will be restrictive in any way, but I would not put it near the MAF, because it may cause turbulence. I will get around to putting it on my HS CAI this spring.

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.
