Product Description

Elevate your engine's intake performance with the K&N RU-3270 Universal Clamp-On Air Filter. Designed to fit virtually any application where the intake flange is approximately 6" (152 mm) in diameter, this filter offers a high-flow, washable solution built for durability and repeat use. Ideal for performance builders, custom installations, and enthusiasts who want a reusable filter with enhanced airflow characteristics.

The RU-3270 features a pliable molded rubber flange that absorbs vibration and accommodates slight sizing variances for a secure fit. With four layers of premium cotton gauze treated for optimum filtration, this unit is built to trap contaminants while allowing better airflow than many stock filters. The washable and reusable design means you spend less over the life of your vehicle and reduce waste compared to disposable filters.

Installation is straightforward: measure your intake pipe to ensure you have an inside diameter of approximately 6.0" (152 mm), slide the filter over the flange, clamp securely, then you're ready to go. Because this is a universal part (not vehicle-specific), please verify fitment and clearance in your engine bay before purchase and installation.
