Magnum FLOW PRO DRY S In take Replacement Air Fil

The Magnum FLOW PRO DRY S Intake Replacement Air Filter is engineered for automotive enthusiasts and mechanics seeking a premium reusable air filtration solution that delivers measurable gains in airflow and engine efficiency. Unlike disposable paper filters, this clamp-on conical design integrates seamlessly into custom intake systems where maximum breathing room is critical—whether you're running a naturally aspirated build or preparing for forced induction. Built by AFE POWER, a brand trusted across the performance automotive community for durability and real-world results, this universal filter addresses a fundamental need: clean air at high volume without choking engine potential.

The Magnum FLOW PRO DRY S filter features a reusable cotton construction with a conical geometry that maximizes surface area while maintaining consistent flow dynamics across the intake tract. The 6-inch base diameter and 4.5-inch top diameter create a tapered profile that reduces turbulence and supports laminar air velocity—critical for carbureted, naturally aspirated, and turbocharged applications alike. At 7 inches tall with a 4-inch flange, it's sized to fit common aftermarket intake manifolds and custom air box designs without requiring extensive fabrication. The dry-type filtration media (versus oil-coated alternatives) eliminates the risk of over-oiling mass air flow sensors, a common failure point in street and track vehicles, while the white cotton core is serviceable indefinitely with compressed air or gentle washing.

The Magnum FLOW PRO DRY S Intake Replacement Air Filter is ideal for engine builders, tuners, and DIY mechanics constructing custom intake systems or upgrading OEM air boxes on street cars, drift builds, and weekend track warriors. Its universal mounting platform and reusable design make it cost-effective for high-mileage drivers who perform frequent maintenance, while the lightweight construction (1.51 lbs) minimizes unsprung mass and intake heat retention. Installation requires only a hose clamp, making it accessible for any skill level; verify your intake tube inner diameter against the 4-inch flange to ensure proper seal. Whether you're maximizing naturally aspirated performance or building a foundation for supercharger or turbo integration, this filter's proven design supports repeatable, measurable airflow improvements.
