Product Details

This engine oil drain plug is engineered to match the original thread pitch and thread diameter, helping restore a proper seal at the oil pan. The steel body and fine-thread M12-1.50 design support reliable service on vehicles that use a 17 mm hex drain plug, including many BMW 330i, BMW X5, Mini Cooper, and Mercedes-Benz C300 applications. Part number 090-088 is a practical replacement when the original plug is stripped, rounded, or no longer sealing correctly.

This part cross-references MTC/Ronak 1044 for the same application.

Common Problems It Can Address
