Has anyone here used AEM Bypass Valve?
If you've used it (on any car model), give me some feedback? I'm trying to find out the limits of this product before I buy it (assuming that I do). I'm getting new intake ideas and I will probably need one if I go ahead with it. Any related info will be appreciated! Thanks ahead of time.

Works fine and will let NO water come in, it was tested on an NSX with the intake in the water and perfect worked. Only thing when you use it make sure you clamp it very tight so it doesnt rattle off. And you really prob dont need though if your not going through lakes

that thing is a waist of money in my opinion. my honda friends use them and they only work if it is completely submerged in water. i had a cold air on my rx7 and i never had to worry about it. it sucked some water in one day but no damage. no rod to bend

I had it in my 2000 Accord V6 Coupe and it works just fine bro...If I was you get it. Better be safe then sorry right?
Would you rather spend $45 on a bypass valve or spend a whole lot of money $$$$ fixing your engine when you get water in it. Looks like an easy pick to me.

With the bypass instructions you will see a disclaimer stating the bypass valve will decrease your horsepower up to 5 HP. Depending on car and model..
Once the valve starts to get weak it will allow unfilter air to enter your engine...
Total junk....

I had an AEM cold air intake on my honda civic and had the bypass on there and it made it slower than stock! I took it off and and had a lot more HP...I wouldn't get it...waste of money man. At least for it was.

Dunno if they "fixed" this problem but there were cases of people having them and the foam actually broke off got into the engine and boom....This is when i was into probes and mx-6's and they ended up buying the guy a new engine but that was when it just came out....i think all is fine now but needless to say they do help prevent water but why use it if you dont have a cold air like me????? personally i dont like them and wouldnt use one...

The problem I see with using one on an RX-7 is we have an airflow meter - if the bypass lets in even a little air, it's a vacuum leak, and the car will run like crap.
I don't see any need to stick the filter in the fender or something like that - shield the filter from the hot air in the engine bay, duct some fresh air in, and call it a day. Going to wild lengths to engineer a cold air setup usually doesn't net any noticeable results, IMHO.

Interesting feedback...I know that this WILL (read:no doubt in my mind) restrict the flow of air some, but for the intake that I'm thinking it would still benefit (actually be a neccessity somewhat). Damn water...rain rain go away...errr I'll stop now.

some people swear that it'll really hurt performance a lot, but I don't buy their stories, sure it'll hurt some, but big whoop, it can be recovered elsewhere to save the life of your $3000+ engine
I have it on my '92 Civic EX (yes I know, but I'm going to slap a turbo on it some day, just for the sleeper effect and so I don't have to drive a slow car around in the winter).. and I hear it opening up occasionally when I'm tooling around in the wet and splash through a few puddles I didn't see.. it's a totally different sound.
And like Flyby said, I think it was Sport Compact Car, they did a test with some clear pipe and submerged a filter with the AEM bypass valve installed on an NSX (yeah, $$$$) and they did a full 3rd gear dyno pull with the thing partly submerged, then fully submerged, and water was never even close to threatening the engine. The one thing they DID find though was when they lifted the filter out of the water, there was still little bits of water in the filter and as it drained towards the bottom, air started coming in the filter again, throwing drops of water around in the pipe, it looked cool, but wasn't really in danger of the engine there either.. so basically if you hear it opening up, get off the throttle and idle out of the lake you're driving in.

Yea, it's SCC I have the issue with the test, but I just wanted to see if any of you guys used the product. I want to know how it works on a pipe that shorter...will it still work the same??? Is there a limit on how short you can take the piping before it loses effectiveness?

Again, there's no need to stick the freakin' filter down where it could be submerged. I would also seriously worry about vacuum leaks.
Stick a cone on, make a shield, be done with it.

IMHO, those things are a marketing gimmick, a product designed to solve a "problem" that isn't even there (or shouldn't be). If you tell someone about a product that will stop their pod filter from ingesting water from deep puddles", they'll think "my God, my engine will die if my pod filter ingests water from deep puddles" and run out and buy one, thinking they actually have a potential problem. But any pod filter that's in a location that could suck up water is just a poorly designed intake. Besides, water spray from wet driving will have little impact, it's only large amounts that will cause problems. If you drive though a puddle deep enough to injest that much water, you need your head read...
