Product Details

Bosch 5445WS is an engine air filter designed to help maintain clean intake airflow in compatible vehicles. The pleated media is engineered to trap airborne contaminants before they reach the engine, while the polyurethane seal helps preserve filter surface integrity and maintain a stable seal under operating conditions. This part cross-references 5016646AA and 6483645 for the same application.

Fitment coverage includes 1999-2003 Dodge Ram 1500 Van, 1999-2003 Dodge Ram 2500 Van, 1999-2003 Dodge Ram 3500 Van, 1989 Dodge D100 with metal housing, and 1970-1974 Dodge Challenger. It also fits 1977-1992 Pontiac Firebird, 1980-1987 Chevrolet Camaro, and 1974-1988 Jeep J10 and J20 applications.

What It Helps Address

• Restricted airflow caused by a dirty or clogged engine air filter
• Dust and debris entering the intake system
• Loss of filtration efficiency in aging filter media
• Seal deterioration from heat, water exposure, or age
• Routine air filter replacement on compatible Dodge, Jeep, and Chevrolet vehicles

Installation Notes and Tips

Verify the air filter housing style before ordering, especially on 1989 Dodge applications noted with metal housing or 10-inch air filter housing. Confirm the vehicle year, make, model, and engine air box configuration against the fitment list before installation. Inspect the air cleaner housing for dirt buildup and replace the filter if the sealing surface is damaged or uneven.
