Baldwin Filters RS4130 Air Filter

Baldwin RS4130 Automotive Air Filter

The Baldwin RS4130 is a radial-design automotive engine air filter supplied as a complete element. It fits engine-intake housings that accept a 5-1/32 inch outside diameter and a 6-1/4 inch height. This filter is intended for vehicle owners and mechanics performing scheduled maintenance on compatible engines.

Radial Element Performance Under Sustained Flow

The radial pleat arrangement maintains consistent airflow as the filter loads with dust during extended driving cycles. Because the element is the only replaceable component, the housing remains in service while the media captures contaminants over the full service interval. Steady pressure drop across the media supports stable engine breathing under continuous load.

Fitment Limits of the Radial Seal Interface

The filter seals on its 5-1/32 inch outside diameter and 6-1/4 inch height, so the housing must match those dimensions exactly for a leak-free fit. Installations with a different seal diameter, taller or shorter cavity, or a non-radial sealing surface will not accept this element. Buyers who need a different sealing diameter or a panel-style filter cannot use this part.
