DISA Intake Air Adjustment Unit

The Genuine BMW DISA valve serves as an intake air adjustment unit, playing a crucial role in optimizing your BMW's engine performance across the entire rev range. By artificially lengthening intake runners at low RPMs, it enhances low-end torque, and by shortening them at high RPMs, it boosts top-end power. A malfunctioning DISA valve can manifest as hesitation at low RPMs, a rough idle, lean engine codes, and noticeable clicking or rattling sounds from the engine bay. This specific unit is considered the lower DISA valve and is typically the culprit behind DISA-related noises. It controls the flap that adjusts the path of air within the intake manifold. Previous revisions of this part include 11-61-7-522-929 and 11-61-7-560-537.

It is essential to use the vehicle selector to confirm exact fitment for your specific BMW.
