Review on JDMSPEED Left Intake Manifold Adjusting Unit DISA Valve Replacement | BMW 135i 328i 530i 528i X5 Z4 by Michael Daniels

Installed in my E83 BMW X3. I immediately got error codes that he wasn't responding. Never worked properly or communicated with the ECM. I removed the component to inspect and found that all of the seals were damaged and melted in less than 60 days. I compared it to the original which has 140,000 miles and the original is in much better condition. Instead, the original part is retained and replaced. See photo. This product is right after only 2 months.
