Air and fuel filters are essential to keep your gasoline engine in good working order. They should be replaced per the manufacturer's recommendations to ensure that the engine receives proper air and fuel flow.
The air filter protects the gasoline engine from the ingress of dust particles , dirt, and other airborne contaminants that can damage the engine and reduce fuel efficiency. Over time, the air filter clogs and loses efficiency, which can negatively affect the performance of the machinery.
On the other hand, the fuel filter prevents impurities from entering the gasoline engine and reducing its performance. The fuel filter can become clogged over time and cause a decrease in engine power, misfiring and even damage to the fuel injection system.
