air filter replacement

What does an air filter do?

Just as humans need oxygen to breath, your car’s engine also needs oxygen to perform the combustion process. The air filter is your vehicle's first line of defence and is designed to only allow clean air into the engine. It filters the air drawn into the engine thus preventing airborne contaminants such as dirt, dust and leaves from getting pulled into the engine compartment.

This relatively inexpensive part protects the more valuable parts of your engine from getting blocked and damaged by dirt in the air. Your engine needs air in order to operate properly, so failing to replace your air filter regularly could result in it becoming blocked. If this happens your engine could be starved of oxygen, and you may need to fork out for more expensive repairs.

How often should an air filter need replacing?

You should change your air filter every 15,000 to 30,000 miles. This varies from car to car, and if you're driving mostly on polluted city streets or dusty roads, it's a good idea to change the air filter more regularly.
