Injen is a leader in the aftermarket performance industry, and they have done it again with the BMW Cold Air Intake. If you are looking for decent horsepower gains, and an increase in fuel economy than an Injen Air intake is the way to go. They come in the following finishes:

• Polished Aluminum
• Black Aluminum

By increasing the air flow to you vehicle, it is burning more air and less gas, therefore increasing fuel economy. Horsepower increases from 15-20 HP, and installation is a snap. Injen Air Intake are manufactured using the highest quality m,aterials and workmanship.

The ideal aftermarket Injen intake system should increase the velocity of the air while it travels to the throttle body, while minimizing turbulence, temperature and restriction of flow. There are many manufacturers of cold air intake systems that use different techniques to achieve increased air flow, reduced turbulence and lower intake temperatures. Injen Air Intake does all this and more.

So, just how does a cold air intake work. I am glad that you asked. A Injen cold air intake is designed to decrease the temperature of the air entering your car to take full advantage of your engine's power. Colder, denser air acts like "food" for your engine, giving Injen the extra amount of power that it needs to perform optimally.

The reason why you want cool air going into your engine instead of hot air is basic science. Colder air has more oxygen molecules because of the higher density. This in turns causes better ignition.

The wider tubes used in Injen cool air intakes allow more air to the engine which in turns improves the operation of your engine which results in increased horsepower and less wear and tear on your engine parts.

We have a wide selection of Injen Cold Air and Short Ram Intakes for the BMW 3 Series. Injen Intake is the best out there.
