Product Description

The K&N RE-1040 universal clamp-on air filter is designed for non-vehicle-specific applications where high-flow filtration and performance are needed. Its 4.5" ID flange, large filter area, and compact height make it ideal for custom intake systems, racing builds, off-road engines, generators, and other equipment.

As a universal part, correct fitment must be confirmed by measuring the intake flange diameter and ensuring sufficient clearance around the filter. Installation is simple: clamp securely onto the intake tube. The washable and reusable design reduces long-term maintenance costs while maintaining consistent airflow and engine protection.
