Product Description

The aFe 21-35009 Magnum FLOW universal clamp-on air filter uses Pro Dry S synthetic media across a durable, all-polyurethane construction, giving builders a no-oil-required filter that outflows a stock paper element. Tall, evenly spaced pleats increase surface area for strong dust-holding capacity, while the integrated urethane bump seal keeps the fit tight and leak-free over the filter's lifespan.

This filter is a solid choice for custom intake builds or replacement needs where a 3-1/2" flange clamp-on filter is required, offering up to a 25% airflow increase over the factory filter for gains in horsepower, torque, and throttle response. Since it's washable and reusable with just soap and water, it's a convenient, low-maintenance option for owners who want consistent performance without the mess of re-oiling.
