A close up of one of our service technicians changing an air filter in a car at Ira Lexus of Danvers.

Your engine needs air to run properly, and that air needs to be as clean as possible. The air filter in your car is what keeps that air clean and allows your engine to run as it should, but from time to time, it will need to be replaced.

The good news for you is that it’s a pretty simple maintenance task. You don’t need fancy tools or a ton of automotive know-how to do it at home. Ira Lexus of Danvers serves drivers across North Andover, Peabody, and Danvers, and has put together this brief guide on how to change the air filter in your car. Contact us with questions or to schedule service.


Outside air can have pollen, dust, dirt, and other contaminants. That’s where the air filter comes in to protect the engine. The air mixes with gas, the spark plug gives the spark, and the engine is able to run as it should. The air filter can increase fuel efficiency, ensure your engine lasts longer, and reduce emissions.

Automakers have different standards when it comes to changing the air filter, but it can come as early as every 15,000 miles, and as late as around 35,000 miles. It’s a good thing when that old air filter is a little dirty and has some dust on it—that means it’s doing its job and keeping that “bad stuff” out of the engine!

You can purchase an air filter at any auto parts shop. To change the filter:


  • Open the hood and find the air filter box. It’s usually sitting on top of or at the side of the engine. There will be a hose sticking out of the side of this box.
  • Open up the air filter box and remove the old filter.
  • Check the filter to see if it needs to be changed. If you see a lot of dirt and gunk, it’s time to replace it.
  • Place the new filter into the filter box, making sure it fits. Close the filter box and snap the clips. That’s it!




Changing the air filter in your car is a simple maintenance task that can be done in the comfort of your own North Andover, Peabody, or Danvers area garage.

If you’re unsure how to change the air filter, or you’d prefer that our experienced technicians handle the issue, we’ll be happy to do it for you. There are also other filters in your car: the cabin air filter, and the oil filter.
