How often should you change your air filters?
Air filters have a simple – but important – job. They help filter dirt and grime from the air before it hits your engine. It’s a quick and easy way to improve the performance of your car.
As a general rule, you should change your air filters a couple of times a year (more often in large metropolitan cities and other places where the air isn’t necessarily as clean as it should be). An easy way to keep track: plan to change your air filters every other time you get your oil changed.
There are plenty of benefits. A Department of Energy study done last year shows that replacing your air filters can improve acceleration on fuel-injected, computer-controlled gasoline engines by 6 to 11 percent. Not a bad deal, is it?
