Automotive engine air filter

This Baldwin Filters PA1688 is a round automotive engine air filter built to fit engines that require its specific dimensions. It serves as a direct replacement element for compatible air-intake housings. The filter is supplied new and ready for installation in passenger cars, light trucks or industrial equipment that match its specification.

Sustained filtration performance

Under continuous engine operation the element traps airborne contaminants before they reach the combustion chambers, maintaining consistent airflow across the service interval. Its round design distributes dust loading evenly around the media, preventing localised restriction that can increase pressure drop over time. Regular inspection and replacement keep the engine breathing cleanly during extended driving cycles.

Round element construction and fit

The round profile with a 2-15/16 in outside diameter and 3-15/16 in height determines which air-box assemblies accept the filter. Builders or technicians must verify that the housing sealing surface matches these dimensions to avoid bypass leaks. The element-only format means no additional frame or gasket is included, so the existing housing hardware must be reused. This filter is not suited for applications requiring a panel-style or rectangular element.

Questions about this item

How much airflow restriction does the PA1688 create when the engine runs continuously?

The round automotive engine air filter uses a 2-15/16 in outside diameter and 3-15/16 in height to maintain steady flow during extended operation.

Which housing or mounting hardware must I already have to install this filter?

The element-only design requires an existing round housing that accepts a 2-15/16 in outside diameter and 3-15/16 in tall cartridge.

Will the 1688 fit the same housing as my older Baldwin round filter?

Match the 2-15/16 in outside diameter and 3-15/16 in height against the previous unit; identical dimensions mean direct interchangeability.
