Rather than targeting a specific vehicle, this filter uses a 5.0-inch flange with a flexible molded rubber base, allowing it to clamp onto compatible intake tubes or housings with relative ease. The cotton-gauze media provides a balance of high airflow and effective filtration, helping engines breathe more freely while still trapping contaminants.\u003c\/p\u003e\u003cp\u003eThanks to its washable and reusable design, the RU-5302 offers long-term value compared to disposable filters. It arrives pre-oiled and ready for installation, which makes it a convenient choice for enthusiasts upgrading or customizing their air intake setup. Because it's universal, proper fitment depends on matching intake tube diameter and ensuring sufficient clearance - so it's best suited for custom or aftermarket intake systems rather than OEM-specific airboxes.\u003c\/p\u003e","brand":"K\u0026N Engineering","offers":[{"title":"Default Title","offer_id":53362937233727,"sku":"KNNRU-5302","price":123.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/fe665715c72b71b31b99f81d9a371564L.jpg?v=1780090187","url":"https:\/\/wcaperformance.com\/products\/k-n-universal-5in-flange-x-8-1-2in-base-x-5in-height-high-flow-air-filter","provider":"WCA Performance","version":"1.0","type":"link"}
