The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems.
Dusty conditions or polluted city driving means you’ll need to change your filter more often. Your technician can check your filter for you. In fact, it’s often a routine part of an oil change.
Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.
