How Often Should You Change an Engine Air Filter?

Although your owner’s manual should include a model-specific recommendation on how often to change your engine air filter, many drivers end up replacing these filters every 30,000 to 45,000 miles. This is a significant margin, and it’s important to point out that many factors can impact the longevity of these components. We’ve covered the basics below so that you can keep your engine performing as intended.

What Does an Engine Air Filter Do?

Your vehicle’s internal combustion engine requires fresh air in order to ignite the fuel in the chamber. An engine air filter cleans the air that gets pulled into your engine and prevents residues from slowing you down! 

The air occasionally carries dirt, dust, pollen, and other contaminants, and the regions near Fairfield and Westport are no exceptions! If your engine air filter is due for replacement, intake of these particles will lead to:

• Unsatisfying acceleration
• Lower fuel economy
• Unreliable spark plugs
• Dark exhaust smoke

If your service engine light comes on, an expired engine air filter may be to blame! Although replacing your filter every 30,000 to 45,000 miles should catch most of these issues before they arise, it’s always a good idea to stick to the recommendations in your owner’s manual. Your owner’s manual should also tell you what kind of air filter to purchase, although you can always ask an expert at our parts department if you’re unsure. 

How Often to Change an Engine Air Filter: Other Considerations

• Maybe there’s been a lot of construction along your commute, or perhaps you’ve been encountering tons of pollen in Stamford. When conditions are working against you, you should change your engine air filter more often!
• Drivers who frequently drive on dirt or gravel roads may find that their engine air filters expire more quickly. Ask us to take a look if you’re concerned.
• Checking and replacing the engine air filter is often a fairly easy task. Check your owner’s manual for the location, and remember to wear a mask and gloves. Have a bag ready for the old filter, too!
