THE IMPORTANCE OF AIR FILTERS
Today’s air filters block up to 98 percent of dust, pollen and other contaminants to keep your engine healthy. A high-quality air filter can grab dust particles down to 5.5 microns in diameter – compared to about 50 microns for the average human hair.
If the car’s air filter isn’t doing its job, then dirt can enter the engine and make its way into the oil supply over time. This can wreak havoc on expensive internal components of the engine, such as the valves and valve seats, piston rings and cylinder walls.
Even before causing expensive damage, a dirty air filter can reduce the airflow into the engine, robbing your vehicle of power, reducing performance and fuel economy.
