The launching of a new era of sophistication begins with the all new SP1988. Combining Injen’s patented and renowned step down process, the patent Air Fusion, the Injen/AMSOIL dry filters and for the first time ever, “Air Intake Horns” proved to be an explosive combination. Injen didn’t stop at creating the best and only dual cold air intake system for the 2007+ 350Z. At Injen, they are committed to engineering the first twin, short ram intake system that continues to build usable power through out the powerband. Injen Technology’s award winning innovations are what allows them to maintain a leadership position while competitors attempt to follow Injen’s benchmarks.
