WTB: OEM Air Inlet Tube/Intake tube M42

[Lee22]

looking to buy an OEM Intake tube for 1991 318is that attaches to the stock airbox from the front grill area, (number 12 in the diagram) Part #13711727097

mine has a crack in it and its causing RPM fluctuations at idle.

I have this part. OP there is absolutely no way a crack in this part can cause idle problems. Anything before the AFM is open unmetered air. I would explore other options such as idle control or test for vacuum leaks.

Many of the hoses were replaced under the intake Plenum, oh well. I still need the part. Shoot me some pictures of it what kind of condition is it in?

Was the intake boot replaced?

The ICV, hoses under the intake, and the main intake boot would be the main causes of idle fluctuation.

all of these parts were replaced, i'm not sure about the ICV though, it was almost 3 years ago.
