Bosch Cabin Air Filter P/N:P3755WS
Bosch C3947WS cabin air filter for the 2009-2017 Chevrolet Traverse and other vehicles filters dust, soot and odors from the air entering the cabin.
A clogged cabin filter can show up as weak airflow from the vents or a musty smell when the fan runs. Those signs can also come from the blower or the HVAC system, so with the engine off, look at the old filter first. If it is packed with dust, leaves or grime, it is due for replacement.
The vehicles it fits include the 2009-2017 Chevrolet Traverse, the 2007-2016 GMC Acadia and the 2008-2017 Buick Enclave. Each takes one filter, and this listing is a single filter.
