Product Description

The K&N RR-3003 is a universal high-flow air filter designed for custom intake systems and performance applications where a standard vehicle-specific filter may not suffice. Its reverse-conical (inverted top) design increases filter surface area and airflow capacity, while the oiled cotton-gauze media maintains strong filtration and engine protection.

Installation is straightforward: clamp the filter's 3-inch flange to your intake tube or adapter, ensuring the 6-inch base diameter and 5-inch height clear the surrounding space. Being washable and reusable, the RR-3003 provides long-term value and helps reduce replacement waste.

Ideal for builders, performance enthusiasts, off-road rigs and specialty equipment, the RR-3003 offers versatility and elevated airflow in one unit. Always verify flange size, clearance and mounting orientation before installation to ensure proper fit and optimal performance.
