Genuine BMW 34336857618 Brake Booster Firewall Seal OEM

The Genuine BMW 34336857618 is an OEM brake booster seal (also known as the brake booster gasket or booster assembly seal) designed to create an airtight seal between the brake servo unit and the engine compartment firewall. This is a factory-original replacement part manufactured to BMW's exact specifications, ensuring a precise fit and proper brake booster function.

A failed or deteriorated brake booster seal can result in vacuum leaks that reduce braking assist, leading to a harder brake pedal feel and reduced stopping performance. Replacing this seal restores the integrity of the power brake system and is a required step any time the brake booster is removed for service.

Key Features:

• Genuine OEM BMW part — manufactured to factory specifications
• Seals the brake booster (servo unit) to the engine compartment firewall
• Restores proper vacuum seal for full power brake assist
• Direct OEM replacement — no modifications required
• Single-use part — cannot be reused or reinstalled once removed
• Covered by BMW's 2-year manufacturer warranty, regardless of mileage
