Product Description

The aFe 24-91031 Pro-5R Universal High Flow Air Filter is a performance-oriented replacement filter designed to increase engine airflow while maintaining strong filtration capability. Built with five layers of progressively finer cotton gauze media sandwiched between a rugged polyurethane top and base, this filter helps enhance horsepower, torque, and throttle response compared to stock paper filters. The open, evenly spaced pleats hold more dust and debris, extending service intervals between cleanings.

This unit is washable and reusable, allowing you to clean and reuse the filter multiple times, reducing long-term maintenance costs. Its universal clamp-on design fits a wide variety of intake systems that accept a filter with a 5.50" inlet and 7.00" base diameter, making it a versatile choice for custom builds, performance upgrades, or replacing worn air filters in many aftermarket applications. The integrated urethane bump seal ensures a tight, reliable connection with minimal leakage.
