What This Air Filter Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust and debris entering the intake system during street or highway driving
• Reduced filtration performance in stop-and-go traffic, short-trip use, and dirt-road conditions
• Moisture exposure that can affect filter media durability
• Fitment issues when replacing an OE-style panel air filter on listed Pontiac and Oldsmobile applications

Installation Notes and Tips

Verify the existing filter dimensions and housing style before installation. This WIX panel air filter measures 13.125 in. outer diameter at the top and bottom, 11.625 in. inner diameter at the bottom, and 2.546 in. in height. Confirm the vehicle uses the listed hood scoop or Ram Air configuration where noted, since fitment varies by application.
