THE RACE TO DEVELOP THE WORLD'S FIRST TUNED AIR INTAKE

The evolution of the entire Injen intake line is paved with industry firsts and innovative designs. Cold air intake design prior to 1996 was a relatively straight forward process, but when OBD II became mandatory for all new vehicles, the game changed forever. Real time monitoring of the vehicle's engine forced aftermarket manufacturers to start engineering their products to perform in harmony with the vehicle's electronics. As the years passed, the OBD II processors became faster and faster, which allowed the ECM (Engine Control Module) to become smarter and adapt to changes and/or modifications quicker.

THE PROBLEM IS IDENTIFIED

In 2003, Injen Technology started designing two separate intake systems; one for the 2003 Mazda 6 and one of the 2002 Subaru WRX. It was business as usual inside Injen's R&D department, but this time, something had changed with the ECM and how quickly it interpreted the information it received from various sensors. No matter what intake tube design the R&D department came up with, the ECM would adjust the air/fuel ratio from one hour to the next to compensate for the changes our intake provided. This might not sound like a big deal to most, but Injen Technology intakes rely on two key characteristics to produce power - improved airflow AND a tuned air/fuel ratio to extract every last ounce of safe power. If the ECU was now tuning around Injen air/fuel adjustments, this obviously posed a severe problem that required revolutionary solutions.
