Injen Technology's new twin intakes for the 2009+ Nissan 370Z not only look impressive, but they are massive, too! Equipped with the only patented MR step-down process available,and air fusion , the Nissan 370Z will command respect with one touch of the accelerator. Boasting an astonishing 15 horsepower and 10 ft/lbs. of torque, these twins will be the envy on the track. In addition, Injen uses the only surface loading, webbed media in all its filters, the same ones used in the US Army's M1 tanks. The Ea nano-fiber blue filter removes 5 times more dust then the traditional (paper) filter media and 50 times more dust then the oiled cotton gauze filter. Injen Technology, the only company with the multi-patented step-down process used for tuning today's sophisticated engines.
