Product Description

The K&N RF-1042 is a premium universal high-flow air filter designed for custom intake systems, high-performance builds, off-road vehicles and specialty equipment where a vehicle-specific filter may not apply. With its 6-inch flange inside diameter and generous footprint, it offers substantial airflow capacity while still maintaining strong filtration through K&N's oiled cotton-gauze media.

Installation is straightforward: clamp the RF-1042 onto your intake tube or adapter matching the flange diameter, then secure with a clamp. Because it is washable and reusable, you'll reduce long-term replacement costs and environmental waste compared to standard disposable filters.

Ideal for performance enthusiasts, custom builders, off-road rigs and specialty equipment, the RF-1042 offers flexibility and high-flow capability in one unit. Always verify intake flange dimensions, available clearance and mounting orientation before installation to ensure proper fit and optimum performance.
