How does this filter protect my Powerstroke engine?

The DPA6109 captures airborne particles, keeping them out of the intake and reducing abrasive wear on internal components. Its multiple pleats increase surface area for more dirt storage without restricting airflow, while the silicone gasket ensures a reliable seal under vibration and heat.

• Deep pleated filter media for increased contaminant capacity
• Heavy‑duty silicone gasket for a tight, vibration‑resistant seal
• Designed to maintain adequate airflow for turbocharged diesel engines
• Third‑party tested dust holding capacity (reported 344.2 g)
