For sale is a used OEM BMW three stage intake manifold. BMW part # 11617559523
Usually used for the three stage intake manifold swap on single stage intake N52/N52N engines (x25i - x28i - certain X3s) for +30~40hp along with a tune.
DISA valves have been tested electronically by hooking up to a N52. Large DISA valve works properly (video showing test: https://youtu.be/daQjzxu_V9k). While small DISA valve feels tight and has no physical rotational play, it does not turn properly during testing. It may be possible to rebuild it. They are sold as is.
Be sure to verify fitment to your vehicle before purchase.
