WIX 46438 Radial Seal Outer Air Filter

Protecting an engine from dust and debris starts at the air intake. The WIX 46438 outer air filter uses a radial seal and a heat‑resistant plastisol frame to create a sturdy barrier around the intake path. When paired with the commonly used 42985 inner filter, it helps maintain clean airflow across a range of equipment, from construction machines to agricultural and industrial engines. The design is built to perform under tough conditions, helping you keep the engine breathing easy under demanding workloads.

Key design and performance features

The filter is engineered with embossed pleats and pleat stabilization beads. This configuration enhances dirt capture while preserving airflow, contributing to a more consistent filtration performance over time. The combination of a robust seal and a reinforced structure helps the filter hold its shape even when used in environments with heavy dust or frequent temperature changes. You can expect a clear, tactile sense of solid construction when inspecting a used unit after service.

• Premium engine protection: Helps keep dust away from internal components and from entering lubricating oil paths
• Precise, durable seal: Heat‑resistant plastisol with pliable seals on the top and bottom walls for a tight fit
• Performance and durability: Embossed pleats and stabilizing beads enhance dirt trapping and extend filter life

Routine maintenance remains essential. Replacing the filter as part of your service schedule supports steady airflow and helps minimize wear caused by contaminants. Always consult the owner’s manual for the recommended service interval and replace the filter using the proper procedures to ensure a reliable seal every time.
