Air filters are designed to prevent dust particles from entering the engines where air and fluids flow.The air cleaner assembly works to provide the engine with a supply of clean filtered air. Air needs to be as clean as possible before it mixes with the fuel and burns in the cylinders of the engine. The air cleaner assembly protects the engine to improve the performance of the engine, enabling it to work as efficiently as possible while increasing its useful working life.

When the air filter is dirty, the engine is forced to work harder resulting in poor fuel economy, higher emissions and loss of engine power. A clogged air filter box can lead to under-performance of the aircon system causing weak airflow from the cabin vents. It can also lead to unwanted unfiltered air in the cabin.

The purpose of the air filter is to protect the engine to enhance performance. Acceleration can improve up to 11% after an old dirty air filter has been replaced. Replace or clean your air filter at the recommended intervals to keep air flowing freely to keep your car running at it's best. Air filters are inexpensive and quick to replace. Most drivers can do this routine maintenance themselves.
