Baldwin RS4678 Outer Air Filter

The Baldwin RS4678 is an automotive outer air filter designed for engine intake systems. It uses a radial design to capture contaminants before they reach the engine. This new filter serves as a direct replacement component for scheduled maintenance intervals. It fits applications requiring this specific part number for proper filtration.

Radial Design and Dimensions

The radial construction arranges the filter media in a cylindrical shape around the center tube. This geometry provides a large surface area for airflow and dust holding capacity within the housing. The unit measures 13 7/16 in height and 6 1/2 in outside diameter. These dimensions determine compatibility with the specific air cleaner assembly.

Fitment and Usage Limits

Correct fitment depends entirely on matching the original equipment part number for the vehicle. The filter is restricted from sale in certain states due to local regulations. It functions as an outer element only and is not a complete filter assembly with a housing. Buyers must verify the exact application requirements before installation.
