Injen Technology has continued their exceptional reputation in performance research and development with the release of their cold air intake system for the 07-08 Mazdaspeed3. Injen incorporates their patented MR Technology into each of their MS3 cold air intake systems, a manufacturing and tuning process that maximizes horsepower and torque while regulating the intake path to maintain the proper air/fuel ratios. This process ensures that you are increasing the power output of your Mazdaspeed3 safely and reliably. On their in-house dynojet, Injen has documented +26 horsepower and +29ft/lbs of torque on the Mazdaspeed3. All Injen MR cold air intake systems for the Mazdaspeed3 are manufactured from 6061 aerospace aluminum with a precision CNC machined mass airflow sensor housing and include a pre-oiled high flow filter element.
