A clean air filter is vital to engine performance. As outside air travels through the intake on its way to the engine, it passes through the air filter. Dirt and debris, harmful to an engine, are trapped in the filter. Over time, as more material is trapped, the flow rate decreases, restricting the engine of the air it needs. If the filter is not replaced, engine power, acceleration, and fuel economy are reduced.
Replacement interval not to exceed 15,000 miles
