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

Purchased in April 2019 for my 2010 328 (N51) coupe. It failed in less than two years. When I replaced it today all the sealing material was gone and the gears inside the valve were broken so the valve would not open or close and would rattle under acceleration. This doesn't save you any money in the long run. My replacement costs about $130 from FCP Euros and it comes with a lifetime warranty. I hope for better quality.
