| Adding an aftermarket intake system to your Ford Expedition is one of the easiest and most cost effective ways to increase you Expedition's horsepower and torque. A 57 series K&N intake system will allow your engine to breathe easier resulting in more power. Better airflow means increased performance and better fuel economy. Another important feature of these intakes is their washable filter. This allows the filter to be used over and over again without having to buy a new one every 15,000 miles which is necessary when using paper filters. If your looking to add power to your Expedition, and get better gas mileage, a K&N 57 series intake is for you. |  (57-2538 shown) |
