PA1637-FN is a Baldwin Filters round automotive engine air filter element with an axial seal, designed for use in Baldwin’s round/oval engine air-cleaner housings. The element measures 11-1/8 inches in outside diameter and 12-1/2 inches in height, providing a precise replacement for compatible Baldwin configurations. As an engine air filter element, it sits in the intake path to capture dust and particulates before they reach the engine, helping maintain clean airflow and protect intake components in typical automotive applications.
