* The specific Charger model and year: Different engines respond differently.
* The quality of the cold air intake: A cheap, poorly designed system might offer little to no improvement, while a high-quality system might yield more noticeable gains.
* Other modifications: Other performance modifications (tune, exhaust, etc.) will interact with the cold air intake's effect.
* Testing conditions: Dyno results can vary based on environmental factors and testing procedures.
While some manufacturers advertise horsepower gains, these are often optimistic claims made under ideal conditions. Expect a gain of perhaps 5-15 horsepower at most in real-world situations. You're more likely to notice an improvement in throttle response and potentially a slight increase in torque than a huge jump in horsepower.
