Product Details

Bosch Workshop Air Filter 5245WS uses a high-velocity cellulose media with a pleated construction to trap airborne contaminants before they reach the engine. The polyurethane sealing edge is engineered to preserve filter surface area while maintaining a stable seal under heat and moisture exposure. This makes the 5245WS a practical replacement choice for owners servicing older GM platforms, including Chevrolet Cavalier, Pontiac Sunfire, Buick Century, and Oldsmobile Cutlass Ciera applications.

This part cross-references Monroe Shocks & Struts (e.g., 24577608) for the same application.

What It Helps Address

• Dirty or restricted engine intake air
• Loss of filtration efficiency from a worn filter element
• Air leakage around a deteriorated filter seal
• Reduced protection from dust and road debris entering the intake
• Service replacement needs for select GM air filter applications

Installation Notes

Verify the panel shape and vehicle application before installation. Confirm the air box is clean, then seat the Bosch 5245WS evenly so the polyurethane seal contacts the housing all the way around. Compatible With 1992-2005 Chevrolet Cavalier, N/A; 1995-2005 Pontiac Sunfire, N/A; 1989-1993 Buick Century, N/A; 1989-1993 Oldsmobile Cutlass Ciera, N/A; and other listed GM applications.
