The engine in your vehicle requires fresh, clean air to run at its best, and a major component of this system is the air filter.

This filter removes dirt and debris from the air to stop it entering into the engine and causing damage.

As with any filter, it requires changing at certain intervals, or when it becomes blocked up. If not replaced, it can cause an increase in fuel consumption and a loss of power, as instead of filtering the air, it restricts the amount of air entering the engine.

Thankfully, it’s a relatively simple process to replace your air filter, making it a job that you can perform yourself at home.

Most auto parts stores, such as Supercheap Auto, carry air filters for all popular makes and models.

Replacement Procedure

  1. The first step is to locate the air box.
  2. Open the bonnet of the vehicle and the air box will be located to one side of the engine. It may be held together will clamps, or screwed together.
  3. Undo the fasteners and lift the top of the box away, to allow access to the filter.
  4. Remove the filter from the box, and inspect it. A good way of checking how blocked it is, is to hold it up to a light source and if the light is difficult to see through the filter, it is time to replace it.
  5. With the filter removed from the air box, inspect inside the box for any leaves or debris and clean out if required.
  6. Slide the new air filter into the box, tighten the fasteners, and you’re done!

Following these instructions will allow you to replace your air filter, but if it seems a little overwhelming, or you are worried about not completing the job safely, it is best to get a professional to carry out the repairs required.
