Detailed Description

The Bosch Workshop Air Filter line is engineered for everyday service work where consistent intake filtration matters. Part number 5966WS uses a panel configuration and a high-velocity cellulose media structure to trap airborne contaminants while maintaining airflow through the intake system. The pleated design increases media area, and the sealed frame helps reduce loss of filter surface during operation. This Bosch 5966WS air filter is a practical replacement choice for Chevrolet Malibu and Buick LaCrosse models listed below.
