    When driving around town, your vehicle's engine needs clean air to burn the fuel – and it needs a lot. In fact, a typical vehicle needs about 216,000 gallons of air for every tank of gas. All that air passes through a filter that catches the dust and dirt. Eventually, the filter gets completely full, and because the filter can only hold so much, dirt starts getting through. At Ponci's Diesel Center in Fortuna, we want to help you get the best air quality in your vehicle, but first, we want to explain the process of where this dirty air is going.
