E60 Afe M5 Stage 2 Intake 2004+

aFe Stage 2 Air Intake System Looking to get A LOT more power out of your M5? An intake is a very easy, simple way to gain power, tone, and performance. Not only do you gain more horsepower, you also gain throttle response, airflow, gas mileage, and engine tone. This intake replaces your stock filters and air boxes. The heat shields will keep hot air from the engine bay out so that only crisp, cold air from outside is coming in. The pre-filters that are provided clean the air before it even reaches your filters, so your vehicle is getting the cleanest and coolest air possible. Installation is very easy with just simple tools.
