Detailed Description

WIX 46338 is an engine air filter engineered for heavy-duty use in 1993 Dodge D250, D350, W250, and W350 trucks. The radial seal style helps maintain a consistent seal at the intake, while the cellulose media is paired with a durable filter body and plastic ends for long service life. WIX HD air filters are built around premium filtration media and structural support features that help maintain filter shape during service intervals. Laboratory testing to ISO 5011 standards is cited by the manufacturer with minimum contaminant removal efficiency of 99.9% based on referenced WIX test samples. This part cross-references Baldwin RS3550 for the same application.

What It Helps Address

• Restricted engine airflow from a loaded or dirty air filter
• Dust and debris entering the intake system
• Uneven sealing at the air cleaner housing
• Reduced filtration performance during OEM service intervals
• Premature intake contamination in heavy-duty truck use

Installation Notes and Tips

Verify the air cleaner housing dimensions before installation and compare the filter height, outer diameter, and inner diameter to the original part. Inspect the housing sealing surface for dirt or damage before placing the filter. For 1993 Dodge D250, D350, W250, and W350 applications, confirm the intake assembly matches the listed radial seal configuration and replace the filter at the manufacturer-recommended service interval.

Quality Assurance

WIX HD filters are manufactured with premium filtration media and durable end-cap construction for heavy-duty service. The manufacturer references ISO 5011 laboratory testing and recommends these filters for OEM air filter change intervals.
