How Often Should You Change the Air Filter on a 7.3 Powerstroke?

According to Ford Motor Company, the replacement interval of an air filter on 7.3 Powerstroke should lie between every 15000 and 30000 miles. But this range may vary if you drive on rough and dirty roads, or if the pollution level around your vehicle is unusually high. In such cases, the air filter should be replaced more frequently to improve the airflow and increase the engine’s lifespan.

In fact, there exists no particular time limit regarding air filter replacement, and eventually, you must identify the vehicle’s decreased fuel economy, sluggish acceleration, poor noises, and condition of the air filter. If any of these signs occur, replace the air filter as soon as possible.

What Does an Air Filter Do?

As the name suggests, air filters clean the air before it reaches the engine by trapping the dust, pollen, smoke, and other contaminants that pose risks to the efficiency of an engine. These products are made of porous materials that sit between the fresh air inlet and engine to catch and block all the dirt in their interstices and make sure that optimal and only fresh air enters the valuable engine.

If a proper filter is not used, this debris accumulates in the engine, and this situation will place the valves, cylinder walls, and pistons in peril. That’s why a vehicle’s long life and engine’s safety are attained by installing an effective air filter.
