Heavy-duty truck filters serve as a protective barrier, ensuring the engine receives a steady stream of clean air and oil free from contaminants and debris. Filters are indispensable in maintaining optimal performance when operating in tandem with other engine components. Air filters specifically are designed to provide maximum surface area to capture impurities, ensuring only clean air enters the combustion chamber. Under regular conditions, a heavy-duty truck’s air filter can last between 15,000 to 30,000 miles. However, this lifespan is influenced by factors such as theenvironment in which the truck operates.
