DescriptionWhen the folks at BMW engineer a car, they cannot focus exclusively on performance. They must take several other factors into consideration, including noise levels and serviceability, and often end up compromising on power output. The air intake system is no exception. In order to keep the engine quiet enough to satisfy the average customer BMW encases the air filter in a plastic housing. This housing restricts the amount of air that can flow through the filter, resulting in a quieter intake but a frustrated engine It's like an Olympic runner being forced to breath through a straw. Let your BMW Breath! Replacing the stock air filter assembly with our Power Flow kit allows more air to enter your BMW's engine so it can breathe as deeply as it wants. The Power Flow filter consists of a cone-shaped K&N filter and necessary hardware.
