The cold air intake system allows your engine to breath much better. The air system sucks in cold, outside air into the engine intake. This provides a more efficient oxygen fuel mix. In return, the engine will provide more horsepower and torque, boosting performance of your vehicle. This is especially for turbocharged vehicles, like the Mini Cooper R53. The cold air speeds the turbo up, making it spool up much quicker.
