I'm really not too sure what it is. It's very small, thinner than a pencil. It went from the end of the intake to the other side of the intake manifold area... it was about a foot... maybe a foot and a half. It's just a tad short... I'm on my way to get another one...

Oh... it's also not all a hose. Most of it is a black hard plastic tube and the ends are grey flexable tubing. I don't know if that makes a diffrence or not... I'm going to a local shop in about 10 mins... so I'll ask them too.
