Radial Seal Air Filter

The WIX RACING FILTERS Radial Seal Air Filter (WIX 46440) is engineered for GM fullsize trucks from 1996 through 2002, delivering reliable engine protection and airflow optimization for vehicles running stock or lightly modified powertrains. As a mechanic, you know that a quality air filter is the first line of defense against dust, debris, and contaminants that rob horsepower and degrade engine longevity. This round filter element addresses the cooling and filtration demands of light-duty trucks during their most critical performance years, making it an essential maintenance component for fleet operators, weekend warriors, and daily drivers alike.

Built with a radial seal design and high-quality paper media, the WIX 46440 creates a secure perimeter seal that prevents unfiltered air from bypassing the element—a common failure point in older OEM filters. The 6.488-inch diameter and 11.122-inch height provide substantial filtration surface area, allowing extended intervals between changes while maintaining consistent air density and fuel trim stability. WIX's racing-grade construction ensures that this filter resists moisture intrusion and maintains structural integrity under sustained engine loads, making it ideal for trucks that see towing, hauling, or spirited highway driving. The white paper media is optimized for the airflow characteristics of these fullsize platforms, preventing excessive restriction that would trigger sensor drift on vehicles without advanced compensators.

Technicians servicing Chevrolet, GMC, and other GM fullsize trucks (C1500, K1500, Suburban, Yukon, and similar models) will recognize this as a direct OEM replacement that improves upon factory filter reliability and filtration efficiency. Installation is straightforward—simply remove the existing round element from the airbox assembly and secure the Radial Seal unit in place with the factory clamp. Whether you're performing routine maintenance at 15,000-mile intervals or upgrading from a degraded original filter, the WIX 46440 delivers the consistent protection and performance that 1996–2002 GM fullsize truck owners demand.
