The engine air filter plays an important role in vehicle performance, preventing contaminants from getting into the engine and compromising safety and drivability. But this crucial auto part needs to be replaced regularly to ensure maximum protection for your engine. How often should you change your engine air filter? In general, our service team at Bayer Motor Company recommends a new one be installed every 30,000 to 45,000 miles. Here is what you need to know about how often to change your engine air filter.



What an Engine Air Filter Does

Before we get into how often to change an engine air filter, let’s look at just what this vital component does for your vehicle. As mentioned above, the air filter traps dirt, dust, sand, and other fine debris and contaminants so they can’t enter the engine and diminish its performance on Stephenville and Brownwood roads. Over time, the engine air filter naturally accumulates some debris buildup. When this buildup is significant, the filter can become clogged, which lessens its ability to protect the engine from contaminants.

How can you tell you need to replace your engine air filter? Look for these common signs:

  • Slow or sluggish acceleration
  • Spark plug misfires
  • Black smoke coming from the exhaust system
  • An illuminated Service Engine light
  • Decreased fuel economy

How Often to Change an Engine Air Filter

So, how often should you change your engine air filter? The general suggestion is every 30,000 to 45,000 miles, but be sure to confirm this by checking your vehicle’s owner’s manual. If you regularly drive on gravel or dirt roads in the Granbury area, in sandy or overly dusty environments, or in congested traffic, especially on hot days, your engine air filter will almost certainly get more of a workout, which means you’ll likely need to change it more frequently.

To replace your engine air filter, open the filter compartment, remove the dirty one, and swap it out with a new one. You can also leave it to the professionals and have our service team at Bayer Motor Company take care of this essential maintenance task for you.
