Currently your car will be either be breathing in warm air from within the engine bay or is trying to suck enough air from a standard undersized and restrictive induction. Cool air forced into a car’s engine is a well-proven way of improving your cars performance. Cool air is mandatory for optimum performance, as it contains more oxygen than warm air and is therefore denser, resulting in a more effective burning of the fuel mix.
Cold air induction systems are designed to channel high pressure cool air from the front of a moving car directly to the air box. This effect of cool air provides superior performance to that of a pod system that filters swirling hot air from within the engine bay with no ramming effect whatsoever.
Your vehicles ECU and/or airflow meter are designed to detect the increased cool air and after the air/fuel mixture accordingly. High-pressure airflow is forced into the engine like a slight supercharging effect.
