Air Intake System 08-13 Infiniti G37 3.7L

The AFE POWER Air Intake System for 08–13 Infiniti G37 3.7L V6 is engineered to maximize airflow to your engine while maintaining reliable operation in real-world driving conditions. This is an essential upgrade for G37 owners seeking improved throttle response and efficiency without sacrificing factory drivability. Whether you're tuning your sedan for spirited driving or simply want to reclaim the horsepower your 3.7L naturally-aspirated engine is capable of producing, this cold air intake replaces restrictive factory airboxes with a more direct path to the throttle body.

AFE POWER's design draws cooler, denser air from outside the engine bay into a high-flow intake tube, which reduces intake temperature and increases oxygen density for more complete combustion. The system utilizes premium materials and precision-engineered components that withstand daily driving while delivering measurable gains in volumetric efficiency. The intake tract is tuned specifically for the G37's 3.7L V6 displacement and cylinder head geometry, ensuring optimal velocity and laminar flow at both low RPM idle and high-RPM acceleration.

G37 enthusiasts benefit most from this upgrade when paired with supporting modifications—such as ECU tuning, exhaust work, or fuel system optimization—but standalone installation delivers noticeable improvements in off-the-line response and high-end power. This intake system is compatible with both the Infiniti G37 Coupe and Sedan models, making it a versatile choice for performance upgrades.
