5 Signs It’s Time to Replace Your Car Engine Air Filter
Car engines need both air and fuel to work correctly. Air flows through the engine via an air filter, which blocks leaves, dust, dirt, and other contaminants from entering. Over time, the filter can get dirty and clogged, and this can have negative effects on the way your engine operates, so it’s important to get filters changed on a regular basis.
1. A Dirty or Discolored Filter
One of the easiest ways to spot a filter that needs changing is to actually take a look at it. A clean and fresh filter will be mostly white in color but will get darker as it gathers dust and dirt. If your filter looks very dark and dirty, it might be time to change it. If you’re unsure about anything, you can get a technician to check your filters.
2. Odd Engine Noises
Cars make a lot of different noises, and you don’t have to worry about every single one. However, if you notice the sudden appearance of spitting or popping sounds when your engine is idle, it’s possible that the filter needs to be changed. These sounds may be caused by filters that have gotten clogged.
3. Check Engine Light
Many drivers notice the “Check Engine” light appearing on their dashboards from time to time. This light can have many different meanings. It could be connected to a filter problem. If the filter is blocked and not enough air is getting through to your engine, the light can turn on automatically. It’s very important to pay attention.
4. Poor Performance
If you use your car regularly, you should have a good knowledge of how it usually feels to drive. If you notice any sudden changes, like slow performance when driving uphill or the car struggling to reach high speeds, it’s possible that it’s the filter.
5. Weak Fuel Economy
A dirty filter can restrict airflow into your engine, and if the engine doesn’t have enough air to operate, it compensates for this by burning extra fuel. This means that you may start to use more fuel.
