Product Description

The aFe 72-91040 Pro-Guard 7 Universal Clamp-On Air Filter is a high-flow performance filter designed for universal use in aftermarket intake setups that accept a 4.5" flange. Built with advanced MagnumFLOW Pro-Guard 7 media, this filter features seven layers of cotton and synthetic materials that deliver excellent airflow while capturing a high amount of dust and contaminants. The tall conical design with evenly spaced pleats increases surface area for airflow and improves filtration capacity compared to many stock and replacement filters.

This clamp-on filter's washable and reusable media allows for multiple cleaning and recharge cycles, lowering long-term maintenance costs and extending service life. The integrated urethane bump seal ensures a secure, leak-free fit when clamped to compatible intake tubes or velocity stacks. Ideal as a replacement or upgrade for intake systems with a matching flange size, the 72-91040 helps improve throttle response and engine breathing when used in suitable applications. Note: This is a universal component and must match the intake's flange size; not CARB exempt and may be restricted in states with strict emissions regulations.
