Induction
availability
Clean air is sucked into your engine’s combustion chamber by your induction system. The air gets metered and measured in the next step, so that your vehicle is able to operate as efficiently as possible. The induction system, of course, can become dirty over time. The airflow in your vehicle can be affected when this happens, making your fuel efficiency decrease. The perfect mix of fuel and air is needed for your car to perform as efficiently as possible. Keep your induction system in good shape so that no other problems arise.
