Detailed Description

WIX WA10424 is an engine air filter for Mazda MX-5, Mazda MX-5 Miata, and Fiat 124 Spider fitments. It is engineered as an OE-style panel filter replacement and is recommended for OEM air filter change intervals. The filter media is built for durability in demanding driving conditions while helping maintain airflow and engine protection. This part cross-references Purolator A21361 for the same application.

What It Helps Address

• Restricted airflow caused by a dirty or loaded engine air filter
• Dust and debris entering the intake system
• Moisture exposure during wet-weather driving
• Reduced filtration performance during stop-and-go or short-trip use
• Routine maintenance replacement for Mazda MX-5 Miata and Fiat 124 Spider service intervals

Installation Notes

Replace the existing panel air filter at the OEM service interval or sooner if driving conditions are severe. Confirm the filter dimensions and housing style before installation, and verify the vehicle application by year, make, and model.
