How often should you change your air filter in your car ?

Frankie is right. If it is not dirty don't change it. You can blow it out with compressed air or just tap it on one of the tires evey time you change the oil. If it looks clean it probably is. Most service centers will try to tell you it needs changing every time. That's how they make money. If it looks dirty to you,go to Auto Zone and get one. They are allot cheaper their.

A lot of that depends on your driving habits and where you drive. Do you live on or have to drive a many dusty dirt roads? Do you drive about 1000 miles a month or 10,000 miles a month? Those are just two questions you need to know the answer to.

At the very least change it once a year, maybe the inspection / plate renewal month. In dusty conditions more often.

When it gets dirty.Check every 1-2 months.

Better yet, switch to a lifetime air filter, like AFE. Get the dry type that can be cleaned with laundry detergent.

Once a year is fine for city driving only. If you live on dirt roads and drive on dirt roads every 3-6 months.

every second oil change or 6-8 thou miles

You should check and clean it at every maintenance service (ie oil change, lube) and if it is too dirty to clean, replace it. You should do a service every 3 months or 3,000 miles, whichever comes first.

every year or if you pull it out and hold it up to the air and look throw it if you cant see any light then change it!!!!!!

Every time you change your oil !
