AF25343/44 Primary Air Filter Cummins® Filtration

The Primary Air Filter, also known as AF25343, is a crucial component of a truck's engine system. This filter is responsible for trapping large particles and debris that can damage the engine. The primary air filter sits between the air intake and the engine and helps to ensure that clean air is delivered to the combustion chamber for optimal performance. Over time, the filter can become clogged with dirt and debris, which can reduce airflow and cause decreased engine performance or even damage. Regularly replacing the primary air filter as part of routine maintenance helps to keep your truck running smoothly while extending its lifespan.
