Genuine BMW – Mini Engine Oil Filler Cap

The Genuine BMW – Mini Engine Oil Filler Cap (also called an oil fill cap or engine oil cap) seals the oil filler opening on the engine's valve cover. It keeps contaminants out and helps keep oil and crankcase pressure in the engine. This is an original equipment part from BMW Group, made to the same standards as the cap installed at the factory.

Key Features:

• Genuine OEM design built to BMW and Mini specifications
• Seals the oil filler port to help prevent oil leaks and keep out dirt and debris
• Twist-on style cap for quick, tool-free removal during oil top-offs and oil changes
• Sealing gasket or O-ring design helps maintain a secure fit
• Made from materials chosen to withstand engine heat, oil exposure, and long-term use

A worn, cracked, or loose oil filler cap can cause oil seepage, contamination, or a loss of crankcase pressure control. Replacing it with a genuine BMW – Mini part restores the correct seal and fit. Select the correct child item for your application from the options on this page.
