1. Bad fuel Efficiency
Your car’s engine needs a balance of air and fuel to be mixed together to run as the manufacturer intended. A bad air filter, will either block air from entering the internal combustion chamber or worse, it will send dirty air into the combustion chamber.
2. Reduced engine performance
Remember that balance of air and fuel we’ve talked about? Well I have bad news: if your air filter cannot supply enough air to your car’s engine, performance is going to take a hit too! Usually, throttle response and acceleration will be affected first, but engine power might suffer too.
3. Bad spark plugs
If you’re running with a dirty air filter, you have a chance to cause the spark plugs to get dirty and even clogged. Needless to say, their performance will be affected.
4. Weird and unusual engine noises
A dirty and even partially clogger air filter will make your engine output coughing like sounds that you would not usually hear. Most of the times these sounds occur when you are running idle. It just means that your engine is not getting enough good air inside of it.
5. Rough idle and sometimes fluctuating idle
After you turn on your engine and just leave it idle, the number of revolutions (RPM) it makes should be in the 900 to 1100 range. These numbers are considered normal. If your car idles a lot higher or a lot lower and even randomly fluctuates without you doing anything… you should check the air filter.
