Although fresh to the BMW intake market, Injen is one of the most experienced and innovative intake manufacturers anywhere. They are one of the original performance intake manufacturers and have years of design and production expertise to share with the BMW market. Injen engineers design their intakes to carefully manage air velocity and air pressure using the Venturi Effect and velocity stacks. Injen tunes their intake designs to make more power but stay within the air/fuel targets set by the BMW engine computer. They also used the largest filter they could fit in the stock locations. With greater surface area and better flow there is more air available to make more power. Each intake filter is protected from engine bay heat using a shield finished with a black wrinkle finish. Fully sealed intakes, like the Injen Evolution series, do a better job of shielding the filter from heat but a more open design produces a better intake sound. We feel the black wrinkle finish looks more at home in a BMW engine bay, however, polished intakes are also available (please inquire).
