DESCRIPTION
The DISA valve (also known as the air adjustment unit) controls the path of air through the plenum, regulating the intake manifold pressure to provide greater torque around town and more power at higher revs. Unfortunately, these are a weak point and can often break, causing the flap to get stuck and allowing debris to potentially enter the motor unfiltered. Located next to the intake manifold, replacement is a relatively simple procedure and should be replaced as part of proper preventative maintenance. This replacement DISA valve units are high quality and a fraction of the cost of a BMW Genuine replacement.
HELPFUL TIPS
A common, yet often overlooked cause of poor performance at low RPM, the DISA valve can be easily diagnosed by unplugging the unit with the engine running. Read about the installation of this DISA valve on our very own E46 by clicking here.
