Installation Notes and Tips

Verify the HVAC intake location before ordering, since listed fitment includes both under-hood and glove box placements depending on model year.

For BMW X3 and BMW X4 maintenance, replace the cabin air filter according to the vehicle’s service schedule or when airflow and air quality begin to decline.
