The K&N Engineering Universal Clamp-On Air Filter offers versatile performance for a wide range of applications including racing vehicles, generators, snowmobiles, tractors, and radio-controlled cars. Designed with adaptability in mind, this filter features a 7-1/2 inch length, a 5-inch outer diameter, and a height of approximately 20-1/8 inches, making it suitable for various equipment setups. Its construction includes ultra-strong molded pliable rubber flanges that absorb vibration, ensuring secure attachment while allowing for slight stretching of up to 1/16 inch (1.5mm) to accommodate different intake sizes. This flexibility makes it an ideal choice for custom or off-road applications where precise fitment can be challenging. The filter's washable and reusable design promotes long-term cost savings and environmental sustainability, allowing users to maintain peak performance through regular cleaning. The K&N universal air filter is engineered to fit applications regardless of the angle or offset diameter of the air intake, providing reliable airflow and filtration across a broad spectrum of equipment. Its durable construction and universal fit make it a practical solution for both professional mechanics and DIY enthusiasts seeking a high-quality, adaptable air filtration system.
