The Speed Pro series intake system for the 09-up Infiniti G37 features special tuning technology for optimal performance gains and a safe A/F ratio. The patent pending technology behind the Mega Ram system constricts the air intake at one point, and then maximizes airflow at other points to supply the maximum amount of air to the intake manifold. Injen SP intakes are also specifically tuned for you vehicle, engine, and engine control unit. Other air intake systems often force the engine to run too lean, risking overheating and other possible engine damage. With the Injen SP, the cold air flow is tuned for optimal performance and engine safety. By reducing turbulence and providing a less restrictive flow through the high performance filter and into the turbo, each intake system is engineered to provide improved horsepower and torque gains over the stock setup. Injen has seen gains of over 15 HP and 10 ft/lbs of torque!

Each 6061, T-6 aluminum alloy intake is finished off with an Injen performance dry air filter with built-in velocity stack. Includes stainless steel clamps, high quality silicone hoses, and instructions.
