Breathe cleaner air on every drive with the MAHLE Activated Carbon Cabin Air Filter LAK173/S (also written LAK173S). It installs as a direct-fit replacement for a range of BMW 7-Series and select ultra-luxury sedans, including the 2010 BMW 740I, 2002-2005 BMW 745I and 745LI, 2006-2008 BMW 750I and 750LI, 2004-2006 BMW 760I, 2003-2008 BMW 760LI, 2007-2008 BMW ALPINA B7, and 2004-2008 ROLLS-ROYCE PHANTOM. A cabin air filter cleans the outside air pulled into the heating, ventilation, and air-conditioning system before it reaches you and your passengers.
Signs the filter may need replacing include reduced airflow from the vents, lingering odors, or fogging that clears slowly. Listed applications use one filter; see the Buyer's Guide tab for the full vehicle and engine list.
