Exclamation AEM Air Bypass Valve WARNING!!!

Well, here's my good deed for the year...

I know most Suby owners won't be using this device, but I thought it would be wise to share this information anyways.

AEM is voluntarily recalling about 3000 AEM Air Bypass Valvles sold between Aug 2000 and Jan 2001. Apparently, under certain circumstances, the valve may come apart and the diaphragm and/or foam spring may be ingested into the throttle body, sometimes forcing the throttle to stick in an open position. Obviously presentng a driving hazard.

More info in the TURBO & High-Tech Performance magazine - Issue August 2001, page 22 - or www.turbomagazine.com

For even more info, call AEM at 310-484-2322 x500 or visit www.aempower.com

Ps. If you have no idea what product I am describing above, you have nothing to worry about.

Default Whoa!

Thanks Tikinet! My husband has an AEM on his Honda (ricemobile!) and was looking at the bypass valves.

I'm glad we haven't bought one yet!

Thanks! Good to know!

Interesting. I've always been a little suspicious on how well those bypass valves work preventing hydrolock, espcieally when they did the demonstration test 'look the engine still runs even thenw the CAI is COMPLETELY SUBMERGED underwater' of course it'll work then, its like the leaky drinking straw effect. But what about partial splashes and stuff? That might not generate enough suction to make the bypass valve work. Or is the oiling on the CAI head enough to keep out little splashes?

Speaking from experience....

I have had CAI on the last three cars I owned... 1994 Integra GSR, 1999 Prelude, 2001 2.5RS and you have got to be kidding me if you think I take it off each time it rains! I have never had a problem with the intake even when it has been soaking wet. Splashes and stuff really shouldn't hurt the intake because it is still sucking in air. Companies (Jackson Racing) actually make products that inject a little water into the intake to cool the intake temps for supercharging so a little water is not going to kill the car.... heck, your gasoline has a certain percentages of water in it.

In the demo of the bypass valve, keep in mind that the car was an NSX and sucks air like nothing else... especially when the big cam take over. I am overall impressed with AEM as a company and in my opinion, I would rather buy a product from a company that is not afriad to recall something to fix it instead of a company that tells you to go to... well yeah....

Just my $.03

I deleted my snorkus (see http://www.remarcable.net/misc/legacy_outback/ ) and my engine now draws air in from the fender well. I went through some mud pits last weekend and got an obscene amount of water and mud all over the car and in the fender wells, etc.

No problems although my Amsoil panel filter looks pretty dirty...... the rest of the intake is clean.

A good filter is a must with any intake!
