Injen Cold Air Intake 2003-2006 Infiniti G35 Coupe/Sedan (Auto & Manual Transmission)Injen Race Division Intake Systems are specifically engineered to deliver peak horsepower and torque. This is made possible by drawing air from an isolated area away from the heated engine compartment. So with the induction of cool air, the engine responds more efficiently, the power band is raised, and peak horsepower and torque are raised. Almost every Race Division application has been designed as a one piece application to ensure smooth air flow.
