What is this part for? (air filter component)

[roony]

Hey guys.

I checked the air filter today to see how dirty it was. I found out that one part that leads out of the side of the air pipe (as in picture) wasnt connected.

So I connected it, and now the engine seems more zippy. At higher revs it is more responsive, and gives off a deeper hum noise. If I was to guess, this extra pipe feeds more oxygen as more fuel burns are higher revs?

I dont know why it wasnt connected before. Thanks

The reason it may have been disconnected was it may of had an aftermarket air intake on it and I think some of them don't use this pipe.

I just marked the photo about what im refering too :). Well im pretty sure the engine was never modified (as per knowledge from the previous owner). But I must say that im happy i connected it, the engine is more responsive now when needed.

That part definitely comes off when an injen is used.

really? im still retaining mine on my injen

the installation manual also says to keep it

[white_ep3_civic]

Yeh it keeps it but u have to disconnect it then reconnect it yen u put the standard box back on. So I'm guessing they forgot to reconnect it when they sold it.
