Bosch Cabin Air Filter P/N:P3877WS
Bosch P3754WS cabin air filter for the 2002-2008 Toyota Corolla and other vehicles traps dust particles from the air before it enters the cabin. It cleans the air that passes through the HVAC system.
A clogged cabin air filter can show up as weak airflow from the vents, a musty smell or more dust inside the car. These signs alone do not prove the filter is the problem; a weak blower motor can cause low airflow too.
This is a direct-fit cabin air filter replacement for the 2002-2008 Toyota Corolla and the 2003-2008 Toyota Matrix, and each takes one.
