When to Replace Your Engine Air Filter

How do you know when it is time to replace your engine air filter? Recording time between air filter changes is one thing to keep track of, but you should also pay attention to signs from your car that the air filter isn’t doing its job. Read on to learn when you should replace your engine air filter.

One thing to be aware of is that you can replace your engine air filter too often. It won’t hurt the car, but you’ll waste money, so don’t let yourself be scammed into getting it done more than once every 15,000 to 30,000 miles. 30,000 miles is a more common interval, but for older vehicles, you may want to change it more often. Some manufacturer’s even say you can wait as long as 45,000 miles between air filter changes.

If you aren’t sure how long it’s been since the last time you got your filter changed, then take a look at it. It should be easy to pop out, and if you don’t know where it is, you can find out using your owner’s manual. Usually you can tell if it’s dirty and not filtering properly simply by looking at it. If you can’t tell, and if it’s been more than two or three years, then consider changing it anyway.

Your fuel economy won’t be significantly affected by an old air filter, but your acceleration speed may drop by up to 11%. So if you notice that you’re not accelerating as fast, check the air filter. For more information about when to change your air filter, give us a call at Crown Kia of Tyler.
