One of the keys to improved performance has always been getting cooler air to your engine. Injen understands this, and this is why they offer their Injen Cold Air Intakes. Cold air has a greater volume than warm air and can thus hold more oxygen. This is important because oxygen is vital to combustion, and more oxygen leads to more complete combustion. With that more complete combustion, more power is produced in your engine’s power stroke, and that leads directly to improved horsepower and performance, to say nothing of the better fuel economy. Injen Cold Air Intakes are made in the United States and are designed to deliver that necessary cooler air to your engine. Cold air intakes by moving air’s point of entry into your engine to a cooler spot. All vehicles have air intakes, but most of those factory intakes are not placed in a spot conducive to drawing in cooler air. These Injen Cold Air Intakes instead draw air from either by the wheel well or behind the headlight, if there is room there. Here, air is cooler. Plus, each cold air intake is designed to also maximize airflow for a smooth, continuous supply of cool air into the combustion.
