Description Reviews MINI Cooper Valve Cover Ground Bolt - This is a USED bolt for the ground point on all Gen 2 MINI's. If you are doing maintenance and lose this ground bolt you need to replace it. It is a very important part on your car. If you start the car without the engine harness hooked up, you can burn out the ECU (which is very expensive to replace). Make sure you have the correct parts to keep your engine safe. Fit all the engines, the N12, N16, N14, and N18. OEM Part #: 11-12-7-559-969 11.12.7.559.969 11 12 7 559 969 11127559969
