Product Details

The Wix 42051 is an engine air filter designed to support clean intake air in vehicles used for stop-and-go traffic, dirt roads, construction zones, short trips, and highway driving.

This part cross-references FRAM CA154 and NAPA Gold Filters 2051 for the same application.

Common Issues It Can Address

• Restricted airflow from a dirty or loaded air filter
• Dust and debris entering the engine intake system
• Reduced filtration performance during frequent short-trip driving
• Moisture-related media breakdown in harsh weather conditions
• Service intervals that call for an OE-style replacement filter

Installation Notes and Tips

Replace the air filter during routine intake service and inspect the air cleaner housing for dirt, leaves, or debris before installing the new filter. Confirm the housing dimensions and filter profile match the listed application before installation. The Wix 42051 is a panel air filter, so proper seating in the air box is important for maintaining filtration performance.

The 42051 is backed by Wix’s filtration testing standards, including ISO 5011 laboratory evaluation, and uses durable media construction for long service life in demanding intake environments.
