I was under my car the other day changing a motor mount and I saw this long black tube sticking down from the air intake tube..... It's just a hollow tube, it rounds off at the end. I have a 95 z28, what the hell is it? what does it do?

 

The the air silencer on the bellows (rubber elbow conected to the throttle body). It cuts down on intake noise.

 

can I cut it off? I don't want anything that is going to make my car quieter!

 

You can get one that is just all bellow. Its a 1le bellow with no silencer. You can get it through jason cromer or slp. I wouldnt really just cut it off.

 

You unfortunately can't just "cut it off" as you will then have a large opening in your intake allowing tainted air to get into your engine = bad.

Some people have done the ghetto rig for it, which is make some sort of fitting that will cover the hole and keeping it there securely.

Or, for approx $40, you can get a 1LE intake elbow, which is the GM intake elbow without the silencer.

 

well duh..... I meant cut if off and cover the hole up..... Why pay 40 bux for it though when I can "ghetto rig" it? it's not anything people will notice. thanks anyways.

 

I've heard the pert plus bottle bottoms make a perfect fit, along with some secure tape (aluminum duct or something of this nature) and whala!

 

You could also get a polished aluminum elbow for $90!

 

Bottom of a shampoo bottle works great. I put it in then siliconed it in place to make sure it wasnt going anywhere. Worked for well over a year until i ended up tearing the elbow in a unrealated situation.

 

It's your cars *******!

I made a perfect plug with a 2x4 and shaped it with a belt sander, fits perfect I even contoured it a little on the inside part to keep it from sticking up too much in the airstream.
