X4XZ Engine Air Filter FA2031 for 2020–2022 Ford Super Duty 6.7L Diesel — Direct-Fit, High Dust Capacity

X4XZ FA2031 is a direct-fit replacement engine air filter engineered for 2020–2022 Ford F250, F350, F450 and F550 Super Duty trucks with the 6.7L diesel engine.

This replacement element matches OE reference FA2031 (fits vehicles using OE LC3Z-9601B, WA10905) and is built from high-grade microfiber adhesive paper to trap fine dust, soot, and road debris before they reach the intake. It’s designed as a value-minded direct replacement for the factory part, providing the filtration performance and dust-holding capacity needed for heavy-duty diesel applications. The pack contains one filter and is straightforward to install during routine maintenance.

How does the FA2031 filter protect my 6.7L diesel engine?

The filter captures airborne contaminants that can accelerate engine wear and clog intake components. By stopping particulates before they enter the turbocharger and combustion chamber, it helps maintain airflow and reduces buildup on sensitive parts.

• High-precision microfiber adhesive paper filters fine soot and road dust.
• Large dust-holding capacity extends service intervals under normal conditions.
• Designed to maintain breathability and engine airflow for consistent performance.
