The DISA valve, otherwise known as the "Intake Manifold Adjuster Unit", is located on the side of the intake manifold and is a common failure item on the BMW M54 engines. The failures are caused by the use of plastic parts for critical components of the DISA valve and the way the parts snap together. At German Auto Solutions we analyzed the way the stock parts fail and engineered a solution that corrects all the problems with the original design. Our repair & upgrade kit replaces the failure prone plastic parts with CNC machined aircraft grade aluminum and titanium pieces. These critical parts no longer just snap together like the stock unit, but are securely locked together using a custom titanium screw and precision machined tapers. By eliminating any possible movement between the two parts, our design eliminates the major cause of DISA valve failures. Why spend $370.00 on a new BMW DISA valve when you can repair & upgrade it with the German Auto Solutions kit for 1/4 the cost. Trust the DISA repair kit purchased by thousands of BMW owners and repair shops world wide.
