Universal Clamp-On Air Filter

The K&N RU-3130 Universal Clamp-On Air Filter is engineered to enhance performance across a diverse range of applications, from racing vehicles to tractors and generators. Its design accommodates various air intake angles and offset diameters, ensuring broad compatibility. These flanges can also be stretched up to 1/16 of an inch (1.5mm) to accommodate intermediate sizes, making installation more versatile. At its core, the RU-3130 utilizes state-of-the-art air filter media composed of four layers of premium cotton gauze. This media is treated with a specially designed tacking agent, creating an intricate mesh that effectively traps harmful contaminants. The filter's rugged construction, utilizing durable, premium materials and advanced manufacturing methods, is intended to provide a lifetime of service. Installation is straightforward, as the K&N air filters come pre-oiled and ready for immediate use, representing one of the most cost-effective vehicle upgrades for quick performance gains. Maintenance is minimal, with cleaning recommended only every 75,000 miles under typical highway driving conditions, equating to approximately five years based on an average of 15,000 miles driven annually. This reusability also contributes to reducing landfill waste compared to disposable filters.
