The AEM Dryflow 21-2259DK Universal Clamp-on Air Filter is engineered for high-performance applications that demand efficient filtration and high airflow without the maintenance of oiled filters. This universal oval-shaped element utilizes AEM’s proprietary oil-free synthetic media, which provides excellent filtration efficiency and simplifies the cleaning process.

Built for durability and ease of installation, this filter features a 4.00-inch flange and a 9.00-inch element length. The integrated filter top design increases total surface area compared to standard closed-top filters, allowing for greater air intake capacity. This makes it an ideal choice for custom intake configurations or replacing worn universal elements in performance setups.
