Genuine BMW Air Flow Meter Intake Boot

The Genuine BMW Air Flow Meter Intake Boot is an original equipment engine air intake hose. It connects the air filter housing or airbox to the intake system. This is the section of the intake tract that carries the air flow meter (mass air flow sensor) connection. Also called an intake hose, intake duct, or air intake boot, it helps keep a sealed, properly routed path for filtered air to reach the engine.

Key Features:

• Genuine BMW original equipment part built to factory specifications
• Flexible construction that absorbs engine movement and vibration
• Designed to seal at the air flow meter and intake connections, helping prevent unmetered air from entering the intake system
• Resists heat, oil vapors, and the under-hood conditions found in an engine bay
• Helps preserve accurate air flow readings for smooth idle, throttle response, and fuel economy

A cracked, torn, or loose intake boot can let in unmetered air. This can cause rough idle, a check engine light, or lean fuel trim codes. Replacing a worn boot with a genuine BMW part restores the original fit and sealing. Choose the variant that matches your part number requirements.
