Outer air filter for automotive engines

The Baldwin Filters RS5558 is an outer air filter designed for automotive engines. It uses a radial element design and is supplied as the filter element only. The product is new and intended for vehicle maintenance or repair.

Radial element handles continuous airflow

The radial construction allows the element to maintain consistent airflow under sustained engine load. It is built to perform during extended operation rather than only in short bursts. The design supports steady filtration over long driving periods.

Dimensions determine correct fitment

The filter measures 8 13/16 inches in outside diameter and 16 23/32 inches in height. These exact figures decide whether the part matches the housing. Buyers who need a different diameter or height cannot use this element.
