Automotive Air Filter
This Baldwin Filters PA1639 is an automotive engine air filter designed for vehicle intake systems. It uses a round, element-only construction and arrives in new condition for direct installation. The filter targets owners and technicians performing routine maintenance on compatible engines. It replaces the original equipment filter when service intervals are due.
Capacity and Headroom
The filter measures 4-13/32 inches in outside diameter and 5 inches in height to match specific housing dimensions. It comfortably handles the airflow and contaminant load defined by the vehicle manufacturer for that housing size. It runs out when the element reaches its dust-holding limit or when the service schedule calls for replacement. No larger or smaller variants are covered by this part number.
Critical Fitment Specification
The 4-13/32 inch outside diameter and 5 inch height are the decisive dimensions that determine whether this filter fits the intended air-box. Verifying these measurements against the vehicle service data confirms compatibility before purchase. The round, element-only design must also match the housing style specified by the manufacturer. No other specification overrides this physical fit requirement.

Questions about this item
Will the PA1639 fit the same housing as my current 4-13/32 in diameter filter?
Yes, the outside diameter is 4-13/32 in, so it matches housings built for that size.
How can I confirm the PA1639 is sealing correctly once installed?
After fitting, inspect the seal for even contact all round and check that the engine draws clean air with no whistle or bypass.
Does the PA1639 come with a new housing or just the element?
The filter is an element only; no housing, clamps or gaskets are included.
