The air filter’s job is to filter the air that goes in an out the vehicle’s combustion system while trapping harmful contaminants; by trapping these contaminants, they do not have the chance to get sucked into the engine where they can cause some serious damage.
As such an important part of any vehicle, the air filter is something that needs replacing fairly often, and is not something you want to leave dirty. Ideally, you will want to change the air filter every 20,000km or 12 months, whichever comes first.
Here are a few warning signs to look out for that tell you your vehicles’ air filter is dirty and needs replacing early:
- Decreased engine power
- Decreased throttle power
- Decreased acceleration
- Poor petrol mileage when this was never an issue before
- An engine that misfires or idles roughly
- You smell gasoline when you are not in the middle of filling the tank
- The check engine light is illuminated on your dashboard
- You notice black smoke coming from your exhaust
