Air filters are essential components in a vehicle’s engine system, designed to trap dust, dirt and other airborne particles before they can enter the engine. By ensuring that only clean air mixes with fuel for combustion, air filters help maintain engine performance, improve fuel efficiency and reduce harmful emissions. A clean air filter also protects internal engine parts from wear and damage, ultimately extending the lifespan of the engine. Over time, air filters can become clogged, which may lead to reduced airflow, poor acceleration and increased fuel consumption. Regular inspection and timely replacement of air filters are crucial for optimal vehicle performance and efficiency.
