When you're first thinking about modifying your BMW for performance, two areas need immediate attention: Intake and exhaust. Headers will help the latter, and for the former, you need to invest in a BMW cold air intake. A BMW cold air intake gets the factory airbox, which is designed in part for power, but in part for noise reduction, out of the loop. With the airbox gone, your new BMW cold air intake will route fresh air from outside your engine bay into the induction system. Your BMW cold air intake will have another important, power-producing feature: A high-flow air filter. This filter helps your BMW cold air intake draw in much more air than it could with a factory filter, while getting the intake air even cleaner. Starting to think that a BMW cold air intake is a winner no matter how you cut it? You're right. And you're a winner too when you buy your BMW cold air intake at our low discount prices.
