Detailed Description

Protec PXA49043 is an engine air filter for light-duty passenger vehicle service. The filter is engineered with cellulose media and a closed-top panel format, with dimensions of 12.69 inches long, 5.03 inches wide, and 2.628 inches high. Protec states that this filter matches the original equipment supplier media area and has been laboratory tested to ISO 5011 standards with a minimum 97.5% efficiency rating, based on PRO-TEC PXA42484. This part cross-references FRAM CA10522 and Baldwin PA10285 for the same application.

Compatible With Audi A4, Audi A5, Audi Q5, and Audi allroad applications across the listed model years, the PXA49043 supports routine intake air filtration for everyday normal driving conditions. The Protec PXA49043 is a direct service replacement for drivers maintaining factory-style air filtration on compatible Audi models.

What It Is Used For

• Replacing a dirty or restricted engine air filter.
• Restoring normal airflow through the intake system.
• Supporting cleaner air delivery to the engine.
• Maintaining routine service intervals on compatible Audi vehicles.
• Addressing reduced filtration performance from a worn filter element.

Installation Notes and Tips

Verify the filter dimensions and panel style against the existing air box before installation. Confirm the vehicle application by year, make, and model, since fitment varies across Audi A4, A5, Q5, A4 allroad, and allroad listings. Replace the filter at the normal service interval or sooner if inspection shows heavy contamination.

Quality Assurance

Protec reports ISO 5011 laboratory testing with 97.5% minimum efficiency for this filter design, and the part is intended to match OES media area for the application.
