Engine idles as low as 1,300 RPM which not only increases fuel economy but also reduces component wear. Direct-line air intake means there are no door inlets, and the rear louvers are designed to deter wind-driven rain. Free air delivery is increased due to a step-up ratio in the air-end. An improved cooling system allows operation at a maximum ambient temperature of 113 °F (45 °C). Safety is enhanced with LED taillights, and a wider stance and large 14″ tires for better towing stability.
