Detailed Description

WIX 42488FR is an engine air filter designed to help keep intake air clean while maintaining the airflow needed for consistent engine operation. The enhanced cellulose media is treated with phenolic resin for added durability against moisture ingestion, and the filter construction includes more media than many original equipment service filters. In laboratory testing referenced by WIX, this filter family has demonstrated high efficiency under ISO 5011 procedures.

This part number is used across many GM platforms, including Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, and Cadillac Escalade models. If you are servicing a 2019 Chevrolet Silverado 1500 LD or a 2019 GMC Sierra 1500 Limited, WIX 42488FR matches the listed original equipment part number 25313349 for those applications.

What It Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust and debris entering the intake system during road use
• Moisture-related filter breakdown in wet driving conditions
• Reduced filtration performance during stop-and-go or short-trip driving
• Service replacement needs for GM truck and SUV air filter maintenance
