Tech's opinion of cold air intake kit

We spend a great deal of time analyzing intake air options with the use of pressure barometers and anemometers placed on various points of the front and hood area.

These smaller inlet sources provide a fraction of air in comparison to what the engine compartment realizes from the core support area, below the front bumper and through the inner fenders when applicable.

A new Challenger receives almost 30,000 CFM at speed from these areas.

The intake tube may work best as nothing more than a cross section to support the MAF sensor, if retained. If an aftermarket tube is legal, there may be gains to be found. The longer the inlet tube and the more transitions it encompasses, the higher the pressure drop and the velocity profile can suffer.

These cars tend to be cooled and face less ambient temperature prior to runs. The key to better performance may be closer to the throttle body rather than what may occur by extending the tract nearer the core support or fender.
