Signs that It’s Time to Change your Air Filter

When it comes to cars, most of us only think of changing something or getting something fixed once we can physically see or hear an obvious problem. But what about those small bits inside that we cannot see? One such ‘bit’ is the air filter.  

What is the air filter?

The internal combustion system engine of your car requires air, fuel and spark to generate power in order for it to run. Air is drawn from outside the vehicle, and then passes through an air filter before entering the engine. The problem with outside air, however, is that it is full of contaminants like sand, dirt, pollen, and more. Without a properly functioning air filter, these things will not be trapped before entering the engine and causing damage.

When should the air filter be replaced?

We recommend maintaining it by getting a new one every 20,000kms or 12 months, whichever comes first. If you live or drive in environments with a high dust level, you may want to consider replacing it even more frequently.

What are some warning signs that the air filter needs to be replaced?

If you experience any of the following before it is usually time to replace the air filter, or if you have never replaced your air filter in the past, it may be time.

  • Decreased engine power
  • Decreased throttle response
  • Decreased acceleration
  • Poor gas mileage
  • Misfiring
  • Rough-idling engine
  • Petrol smell while driving
  • Black smoke
  • Check engine light is on
