Bosch Cabin Air Filter P/N:P3808WS
Bosch C3503WS cabin air filter for the 2003-2008 Mazda 6 cleans the air that enters the cabin through the HVAC system. This Bosch cabin air filter is a charcoal-type filter that targets odors and small airborne particles.
Weak airflow from the vents, odors in the cabin or dust on the vents can mean this filter is worn out, though a blower motor or blower resistor can be behind them too, so find the cause before replacing it.
It fits the 2003-2008 Mazda 6, including the L4-2.3L and V6-3.0L engines.
