The K&N Engineering RU-1037 Universal Clamp-On Air Filter is designed for a broad range of automotive, powersports, motorsport, generator, tractor, snowmobile, and other equipment applications. Its universal design accommodates air intake systems with varying angles and offset diameters, making it a practical solution when a direct-fit replacement is not available.

The filter features a strong, pliable molded rubber flange that helps absorb vibration and provides a secure connection to the intake tube. The flange can accommodate slight variations between sizes, while the clamp-on design supports straightforward installation. The reusable filter media can be cleaned and serviced rather than discarded, helping reduce replacement frequency when maintained with the appropriate K&N filter care products. The RU-1037 is also compatible with the optional RF-1037DK Air Filter Wrap and K&N 99-5000 Filter Care Service Kit Aerosol.

Potential applications include select 2002–2004 Nissan Frontier models and select 2003–2006 Nissan 350Z models; verify intake size, clearance, and vehicle-specific requirements before installation. This product is not CARB approved, and a California emissions compliance acknowledgement may be required. The filter is backed by a 1-Year Limited Warranty.
