The valve cover is responsible for sealing the internal workings of the engines' top end. Most vehicles require a replacement gasket at some point or another and newer models have plastic valve covers that get brittle and crack with age.
Issues with a valve cover such as cracks and warping can result in a major vacuum leak and result in very poor performance. This Original BMW replacement from ECS Tuning will fit and function just like the stock part and will have your BMW running great again in no time. Don't forget to add a new gasket and spark plug seals, available elsewhere on the site.
