Product Overview

The engine air filter, OEM number A0040943504, is fitted to the Mercedes-Benz Actros and Axor heavy-duty truck platforms, covering the OM457, OM501, OM502, OM541, and OM926 engine families, also cross-referencing to related Scania DC9-DC13 engines. Since this filter spans two of Mercedes-Benz's core commercial truck platforms across multiple engine variants, it's a high-turnover part number worth stocking in volume for distributors serving Mercedes-Benz commercial vehicle demand.

A worn or clogged air filter typically shows up as reduced fuel economy, sluggish acceleration, or visible dirt and debris buildup on the filter element. GSK Auto manufactures this air filter to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is an Engine Air Filter?

Function: The engine air filter removes dust, dirt, and debris from the air entering the engine, protecting internal components while allowing sufficient airflow for combustion.

Working Principle: Air drawn into the engine passes through the pleated filter media inside the housing, which traps contaminants while letting clean air through to the intake system. Over time, accumulated debris restricts airflow and reduces filter efficiency.

Importance: On a heavy-duty truck platform running long daily mileage under sustained engine load, a properly functioning air filter is essential for protecting the engine and maintaining performance.

Common Failures & Signs: Visible dirt, dust, or debris buildup on the filter element. Reduced fuel economy from restricted airflow. Sluggish acceleration or reduced engine performance. Darker exhaust smoke from an overly restricted filter.
