Installation Notes

Verify the vehicle’s year, model, and HVAC filter location before installation. Fitment varies by BMW platform and position, including front and rear applications on select models such as the X7.

For best results, replace cabin filters at regular service intervals and inspect the HVAC housing for debris before installing the new filter.
