Genuine BMW Air Intake Boot

The Genuine BMW Air Intake Boot (also called an air intake hose, air inlet duct, or intake tube) is an original equipment component. It connects the air filter housing or airflow sensor to the throttle body or turbocharger inlet on the engine. It carries filtered air to the engine and helps keep unfiltered air out of the intake path.

Key Features:

• Original BMW design that matches factory fit and function
• Flexible molded construction that absorbs engine movement and vibration
• Helps keep the intake system sealed for correct airflow metering
• Built to handle underhood heat, oil vapor, and pressure changes
• Supports smooth engine performance and fuel efficiency

A cracked, torn, or loose intake boot can let in unmetered air. This can cause rough idle, a check engine light, or lower performance. Replacing a worn boot with a Genuine BMW part restores the factory seal and airflow path. Choose the specific variant for your application from the options on this page.
