Bosch 5146WS Air Filter

Bosch Workshop Air Filter 5146WS

The Bosch Workshop Air Filter 5146WS is an engine air filter built for direct-fit service on select Acura and Honda applications. It uses a panel-style design with a high pleat count and cellulose cured media to help keep outside particles out of the intake stream while maintaining airflow for engine protection.

For drivers searching for an Acura TSX air filter or a Honda Accord engine air filter, Bosch 5146WS provides a service replacement built around filtration efficiency and sealing performance. The polyurethane seal helps maintain the filter surface and adds resistance to water and heat exposure.
