Detailed Description

Part number 11127507217 is a brake booster vacuum pump seal engineered for BMW vehicles that use a vacuum pump mounted to the valve cover. The seal is manufactured to OE specifications for correct fitment and sealing, with a round AEM rubber construction that resists heat and age-related deterioration. This makes it a practical replacement when the original seal no longer maintains a tight vacuum seal. This part cross-references BMW OE 11 12 7 507 217 for the same application.

Installation Notes and Tips

Inspect the sealing surfaces on the vacuum pump and valve cover before installation. Clean away oil residue, old seal material, and debris so the new seal can seat evenly. Verify the seal dimensions and application match your BMW model before reassembly. For best results, install on a cool engine and confirm the pump mounts flush after the seal is positioned.
