With the rising innovations in factor engine management comes the need to over come their advance adaptivity to produce any kind of meaningful horsepower. Injen Technology's air intake system with MR technology (replacement reservoir bottle) does exactly this. Through a series of engineered and tested air- restricted sections, the pressurized mass air is controlled to a calculated aggression, allowing for a proper air/fuel calibration. The end results allows for more reliable and consistent horsepower/torque gains. This technology is availed to the sports compact market exclusively through Injen Technology's SP line of intake systems.
