Engine Air Filter Replacement

How often should you replace your engine air filter? Why should you replace your engine air filter? How much does an engine air filter cost? Let’s explore the answers to these questions.



When is the last time you have your engine air filter replaced? Replacing the engine air filter is sometimes a service drivers overlook and having a dirty engine air filter can have a negative effect on your vehicle’s performance. You see, the reason the engine has the air filter is so that it can prevent dirt, dust and other debris or contaminants from getting into the engine. So really, its job is to get dirty so your engine won’t. But what happens when it’s dirty and not replace periodically? Well, the filter gets clogged and restricts air flow to the engine. This may decrease the efficiency of your engine and can lead to other problems.

Do you replace your engine air filter every 15,000-30,000 miles or as your owner’s manual recommends? Sometimes, it may even be advised that you change your engine air filter more often based on where you drive – like if you travel over gravel/dusty roads.

As engine air filter replacement is a maintenance item, your vehicle will perform at its best if you change it according to the owner’s manual. But if you drive on dusty roads and you might be able to tell if the engine air filter needs to be replaced sooner by looking at it – if it has dark areas on the section through which the outside air comes through, then it’s probably best to replace it.

If your vehicle is older than three years or has 30,000 miles or more on the odometer, you’ve never replaced the engine air filter and you can’t tell if it’s clogged by looking at it, you should probably replace it now.

How much does it cost to replace the engine air filter in your vehicle? Depending on the type your vehicle requires the cost varies between $15 to $40 + tax. If you are handy, this may be a service you can perform on your own – just make sure you buy the correct engine filter replacement and reattach everything securely.
