Overview of the K&N High-Flow Universal Clamp-On Air Filter
When it comes to design and build, this filter impresses with its round tapered shape and ultra-strong molded pliable rubber flange that ensures a snug and vibration-resistant fit. The five-layer cotton gauze, treated with a proprietary tacking agent, forms a dense yet breathable mesh that excels at filtering out harmful contaminants without restricting airflow. Its pre-oiled and ready-to-install construction makes the upgrade straightforward, minimizing downtime and effort. Built to last a lifetime, the robust materials and precision engineering give it a premium feel, with durability that outlasts traditional disposable filters.
Performance-wise, the design intent is clear: increasing airflow for enhanced horsepower and acceleration. Routine maintenance is simplified since the unit only needs cleaning every 75,000 miles (about 5 years) under normal driving conditions, saving both time and money over its lifespan. Beyond vehicle benefits, switching reduces landfill waste by substituting disposable filters with a reusable model. To keep it performing optimally, we recommend regular inspection and cleaning per the manufacturer’s guidelines. Below is a quick-reference summary of key specs and benefits:
