3 stage manifold tube?

e90dante · 11-09-2024, 03:09 PM

so i picked up this manifold from a 330i at the junkyard (im broke)
i noticed that it had this tube sticking out that my stock manifold doesnt have, i probably grabbed the wrong one knowing my luck but i want to double check with the experts.

BMW calls this "Oil extraction line". It's attached to the top or the oil separator in your pic, the other end attaches to the plastic angle piece that fits between the throttle body and the intake pipe. If your car didn't have the tube the nipple near the throttle body will be capped.
