The K&N Engineering Universal 2.5 inch Mounting Flange 6 inch Long air filter element (RD-0720) is a reusable cotton performance air filter designed for high-flow intake applications across a wide range of vehicles. This clamp-on mounting flange assembly delivers the hallmark K&N advantage: a washable, reusable cotton media that maintains airflow efficiency while extending service intervals far beyond disposable paper filters. The 2.5-inch mounting flange and 6-inch length accommodate diverse intake configurations, making it a versatile choice for custom air intake systems and performance modifications.
The 2.5-inch flange diameter provides a secure clamp interface for reliable sealing, while the 6-inch length accommodates various engine bay layouts and intake tube routing scenarios. K&N's cotton gauze media is engineered to maximize airflow while filtering particulates, a balance that translates to improved volumetric efficiency under load compared to restrictive OEM filters. The reusable design means this filter can be cleaned, serviced, and reinstalled dozens of times over its service life, reducing long-term consumable costs. Weighing 0.65 lbs, the assembly is lightweight and suitable for both street and performance driving applications where increased air volume supports horsepower gains.
This universal mounting flange is ideal for builders and enthusiasts fabricating custom cold-air or ram-air intake systems, as well as those upgrading stock intake paths with performance-grade filtration. The 2.5-inch flange size works with standard automotive hose clamps and adapters, making it straightforward to integrate into existing or new intake plumbing. Whether you're tuning a street vehicle for responsive throttle feel, supporting an engine modification package, or simply seeking a high-flow alternative to factory filtration, this K&N universal element delivers measurable airflow improvement and the convenience of wash-and-reuse operation that defines the brand's market position.
