Engine Air Filter Replacement

When your technician changes your engine oil and filter, he will also inspect your air filter. You shouldn't need a new air filter at every oil change, but you will need to change it regularly. Listen to your technician's advice if they recommend that you change your air filter.

An air filter does what its name implies: it filters stuff out of the air. Air is drawn into your engine through the filter because your engine needs air to burn fuel. If the filter weren't there, a lot of dust and debris would get into the vehicle's engine. That dust and debris would get hot, burn and produce all kinds of ash and gumminess and would eventually clog up your engine.

Drop in an air filter and voilá! Problem solved.

Air filters themselves however will get clogged up with all the dirt and debris they clean out of the air and this starts blocking  the airflow into the engine. Blocked airflow will reduce engine efficiency and increase fuel consumption.

It's also one of the simplest elements of routine preventive maintenance – and it protects against damage to expensive vehicle electronic systems. No one should have an excuse to drive their vehicle around with a dirty air filter.

Engine Air Filter

Today we want to talk about your engine air filter.

That's the filter that cleans the air before it's burned in your engine. Many people in New Zealand wonder how often they should change their engine air filter. The simple answer is 'when it's dirty'. That's a function of how much air has passed through the filter, so your manufacturer will recommend a mileage interval for replacing the air filter. But you can imagine that how dirty the air is would affect how quickly the filter gets filled.

If you drive in New Zealand where there's lots of dust, pollution or pollen, your engine air filter will get dirty more quickly and need to be changed sooner. That's why we check the air filter with every full-service oil change at Oil Changers. We can visually tell if the filter needs to be changed.

Your filter can only hold so much dirt. Once the filter is full, dirt will pass through to the engine. This dirt gums up the combustion chamber and hurts fuel economy and may cause damage. It can also contaminate the Mass Air Flow Sensor which will affect drivability and can be fairly expensive to replace.

A dirty air filter would also restrict the amount of air that gets to the engine which hurts fuel economy. We can replace your engine air filter with one that matches the factory specifications or you can upgrade your filter for enhanced performance.

So when your service advisor at Oil Changers shows you your dirty air filter, you know how important it is to get it replaced.
