The K&N Engineering Universal Rubber Air Filter with a 2.125-inch flange ID is designed to provide reliable airflow for a wide range of applications including racing vehicles, generators, snowmobiles, and tractors. Crafted with durable, molded pliable rubber flanges, this filter absorbs vibrations and ensures a secure fit across various setups. The flanges can be stretched up to 1/16 inch (1.5mm), allowing for versatility in fitting different intake diameters and angles. This feature makes it suitable for custom installations where precise fitment is essential. The tapered oval shape measures approximately 3 inches by 4 inches and stands about 2.75 inches tall, offering an optimal balance between airflow capacity and compact size. The filters are washable and reusable, making them an economical choice that reduces waste and maintenance costs over time. Proper maintenance involves periodic cleaning to ensure optimal performance, especially in demanding environments like racing or off-road conditions. The K&N universal air filters are built to withstand harsh conditions and provide consistent airflow, contributing to engine efficiency and longevity. These filters are not CARB approved but require acknowledgment of this status during installation. With the flexibility of the pliable rubber flange and the high-quality construction, this filter is an excellent choice for enthusiasts and professionals seeking a versatile, durable, and reusable air filtration solution.
