what is this?

what is that long plastic piece that is hooked into the intake elbow piece and what purpose does it serve?

it came apart from where it was attached and my belt rubbed a hole in it. will this hurt anything or affect performance?

thanks, russell

You talking about the long piece that goes down? If you are, it's the donkey ******* and is a silencer...most people get the 1LE elbow as a replacement to get rid of that.

first off what year is your car I hope 93.Anyway that is the intake silencer(like a muffler)If there is a hole in it your car is getting air that is not going through the maf.You can get the 1le replacement for it that deletes that piece.

Its a "silencer" tube. You don't need it, but the hole in the elbow needs to be plugged up, or you will be letting unfiltered air into the engine, and on 94 and up, bypassing air around the mass air sensor.
