Air Filter Information

An air filter works hard to prevent debris from entering the car’s engine. The fuel-air mixture that your car relies on to propel you forward is cleaned by the air filter, which removes dirt and debris before the airflow reaches the engine. A constant flow of clean, fresh air also prevents your car from overheating. All of the above are damaging to your car’s overall performance, but as well as this, air filters play a huge role in your car’s efficiency and lifespan.

To find out where your air filter is located, check your vehicle’s handbook. The air filter may be found under the bonnet or behind the glove box.

How often you change your air filter will vary between vehicle makes and models. Typically manufacturers recommend they are replaced in an annual service or every 15K to 30K miles. If your air filter is faulty or needs replacing, dirt and grime can also mix with the oil that is supplied to the engine, over time wearing away the components of the engine.

You can change your car filter at home by following our guide with step-by-step instructions and a checklist of what you need to get the job done.
