If you're on a budget or don't have a lot of time to work on your vehicle, don't think you have to forget about getting more performance or fuel mileage from your car or truck. The aFe Stage 1 Cold Air Intake System is inexpensive and can be installed in an hour or less with simple hand tools. This system replaces your factory air filter and airbox with an aFe Pro DRY S air filter and a one-piece open element airbox/heat shield that seals against the hood, isolating the filter from engine heat. The increased flow of cooler air to your engine will result in noticeable gains in power and performance. Cooler, denser air contains more oxygen, and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output.
The one-piece airbox/heat shield is made of rugged 16-gauge powder coated steel. It installs easily in place of the factory airbox; no cutting or drilling is required. The box/shield is attached with quality stainless steel hardware that is supplied with the kit. A specially developed 3-angle velocity stack smoothes the airflow transition from the air filter to the intake tube. Top quality, flexible rubber trim at the top of the box/shield seals against the hood when it is closed, shielding the air filter from engine heat and allowing it to take in cooler air. Some systems include a powder coated steel or brushed aluminum cover to further shield the filter.
The Pro DRY S filter combines high airflow and filtration efficiency with the convenience of oil-free maintenance. It contains 2 layers of randomly porous synthetic fabric, which allows approximately twice the airflow when compared to a typical stock air filter. The increased airflow results in more horsepower and torque, better throttle response and more miles per gallon. But this improved airflow and performance hasn't been gained at the expense of engine protection. The Pro DRY S has an excellent 99.2% filtration efficiency rating.
The pleats in the Pro DRY S are evenly spaced for greater dust holding capacity and the tips are rounded for better airflow. They're also 30% deeper than comparable aftermarket air filters for longer service intervals and greater dust holding capacity. The sealing surface and supporting structures are made from 100% polyurethane, to withstand extreme engine temperatures.
The aFe Stage 1 Air Intake System comes complete with everything necessary for installation, including comprehensive instructions. It’s backed by aFe's limited 2-year warranty and made in the USA.495.00Brand: aFe Part Number: 51-10461 UPC: 802959510476
