Air Cleaner
Cummins®

An air cleaner is a component of a truck's engine that serves to filter out debris and contaminants from the air that is drawn into the engine. The air cleaner, also known as an air filter or intake filter, typically consists of a housing with a replaceable paper or synthetic fiber element inside. As the engine draws in air for combustion, it passes through the air cleaner where any dirt, dust, or other particles are trapped by the filter element. This helps to prevent these contaminants from entering the engine and causing damage over time. Over time, the filter element will become clogged with debris and require replacement to maintain proper airflow and performance. Proper maintenance of the air cleaner is important to ensure optimal engine performance and longevity. Part number 43667 refers to a specific type of air cleaner that may be compatible with certain makes and models of trucks.
