This PA-series part is classified as an oval engine air filter, featuring a short profile suitable for tight spaces and maintaining a solid seal against intake pressure fluctuations. Its dimensions place the overall height at 3-5\/8 in, with the longest exterior axis spanning roughly 3-25\/32 in to 4-13\/32 in, highlighting its compact, engine-ready footprint. This makes PA3957 a direct drop-in replacement for equipment that lists Baldwin PA3957 in its filter requirements, and it is widely cross-referenced in external catalogs and OEM-equivalent listings, including references to Fleetguard AF25474, Hastings AF2422, and other PA3957 cross references. In practice, it serves engines and machines that depend on Baldwin PA-series oval air filters to prevent dust and particulates from entering the intake, helping protect performance and longevity in both automotive and industrial applications. \u003c\/p\u003e\u003c\/div\u003e","brand":"Baldwin","offers":[{"title":"New","offer_id":51660533727534,"sku":null,"price":36.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_abecdddb-2d01-4884-9f92-c71b11b4b961.jpg?v=1769538967","url":"https:\/\/plgautomation.com\/products\/baldwin-pa3957-air-filter","provider":"PLG Automation ","version":"1.0","type":"link"}
