"This high performance CAI effectively opens up the intake system of Ford's Fusion Sport 3.5L V6 power plant and allows it to breath much more freely than the stock intake system allows. 

Our engineers started with a large surface area high-flow nano-fiber air filter, added our famous “race-tested” velocity stack entry and then designed a stainless steel heat shield with a durable rubber gasket to seal the shield against the vehicle’s hood to prevent hot underhood air from being drawn into the airbox from the engine compartment. 

Competitive intakes don't even bother to use a head shield on their intake designs, and do not also provide a velocity stack which increases air velocity and streamlines the incoming air charge providing a clean mass air flow signal. 

Streamlined airflow over the mass air sensor prevents turbulence across the mass air sensor. A clean mass air flow sensor signal is critical to perfect driveability and throttle response. 

This intake was designed to work with the stock engine calibration and will provide a gain of up to 12hp at the wheels on its own."
