Air by-pass valve (Good or bad for performace?)
I have a AEM cold air intake. I installed the by-pass right under the hole where you have the screw on to tighten the pipe. Does the by-pass restrict any hp gains? Meaning does it restrict air? I'm only assuming because I don' t know if the by-pass is considered to be an extra hole in the pipe. Plus it was louder before I installed the by-pass because I had the filter where the by-pass valve is now.(Meaning the pipe was shorter but filter was still in a cold area.

I'm not sure exactly how you have the by-pass installed... it should be installed about half way down the pipe where the pipe itself disappears into the wheel well. Most literature, etc. claims there's no HP loss. I tend to agree. I didn't feel a difference with vs. without it, but it's possible you're loosing maybe 1hp or so.....

I have an AEM CAI.
I used to have a bypass valve. I took it off because I had those very same questions.
I want to say I notice a difference, but it's probably all in my head. I'm not going to put the bypass valve on because I'm lazy and still believe it's better off without it.
Hope this helps.

I have the by-pass valve right under the hole where the pipe disappears. Without the by-pass, the filter is still down in that area but right where the hole is where it disapppears. (technically the pipe would be a little shorter) Which was probably louder because the filter was closer up.
