Specs & Features Air Filter: Red (Non-Oiled) Increases horsepower and torque Replaces stock air box, air filter and intake tubing Cold Air Dam panels block out hot engine bay air Easy to install using commonly available tools Easy to clean oil-free synthetic air filter Washable and reusable air filter media No Hassle Lifetime Warranty Product Description The AIRAID Cold Air Dam (CAD) Air Intake is engineered to give your engine larger amounts of cooler air to produce more horsepower and torque. The intake system retains the original location of the air filter but delivers a big boost with the addition of a huge open-element air inlet protected by Cold Air Dam panels that help to provide a steady, free-flowing supply of cooler outside air into your engine. The panels mount in the factory air box location and utilize any factory cold air inlet ducts that are present, while adding additional cold air passages to the filter. The panels also keep the filter isolated from the hot engine compartment air by sealing to the underside of the hood via blade-style weather stripping. This CAD system utilizes a replacement low-restriction intake tube. The 360-degree conical AIRAID premium air filter is washable and reusable, less restrictive than traditional paper, and assures superior filtration. The AIRAID Cold Air Dam Air Intake is easy to install with common hand tools. Some AIRAID air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.
