Bosch Cabin Air Filter P/N:P3808WS
Bosch P3720WS cabin air filter for the 2000-2014 Chevrolet Impala and other vehicles traps dust in the air entering the HVAC system. This Bosch cabin air filter is a particulate type with no HEPA media.
Weak airflow from the vents, a musty smell or extra dust inside the cabin can mean the filter is clogged, though the blower motor or the HVAC ducting can be behind the same signs, so find the cause before you replace the filter.
This particulate filter fits the 2000-2014 Chevrolet Impala, the 2005-2009 Buick LaCrosse and the 2014-2016 Chevrolet Impala Limited, with one filter per car. Bosch car filters of this kind are designed and tested as direct OE replacements. Open the "Vehicles it fits" section to check your exact model and engine.
