Genuine 65 21 1 376 008 BMW OEM Antenna Base Seal Gasket

The Genuine BMW 65 21 1 376 008 is an OEM factory-replacement antenna seal designed to maintain a weathertight connection between the antenna base and the vehicle body panel. This precision-molded rubber gasket sits between the antenna mast assembly and the mounting surface — typically the roof or rear fender — sealing out moisture, wind noise, and road debris from penetrating the vehicle interior.

Using a Genuine BMW part ensures an exact factory fit with no trimming or modification required, preserving the integrity of your vehicle's body and electrical antenna circuit. Over time, original antenna seals can harden, crack, or compress permanently, leading to water leaks, corrosion around the antenna mount, and interior water damage. Replacing the seal at the first sign of deterioration is a simple, cost-effective way to prevent more extensive repairs.

Key Features:

• OEM Genuine BMW part — exact factory replacement
• Precision-molded rubber construction for a durable, weathertight fit
• Seals the antenna base against water, wind noise, and debris intrusion
• Prevents moisture damage and corrosion at the antenna mounting point
• Direct drop-in fit — no cutting, trimming, or modification required
• Manufacturer Part Number (MPN): 65 21 1 376 008

For best results, inspect the antenna seal whenever the antenna mast or base assembly is serviced. This is a straightforward DIY replacement that restores factory-level weatherproofing to your BMW's antenna installation.
