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.

This intake for the Ford 7.3L Power Stroke diesel is our easy to install QF (Quick Fit) series. This intake benefits from the CAD (Cool Air Dam) that keeps a dense air charge into the engine. There is also a provision to maintain the factory “Filter Gauge” that allows for easy filter monitoring. This ensures you'll know when it's time to service the filter for optimum performance.
