Cold Air Intake for Infiniti G37 (2008-2013) 3.7L Engine - Red

Performance Red Induction: High-Flow Cold Air Intake for the VQ37VHR Powered Infiniti G37

Who It’s For: Engineered for Infiniti owners running the high-revving VQ37VHR powerplant who are tired of the stock sluggishness and the muted, sterile sound of a factory-choked engine bay.

The Symptom: The factory intake on the VQ37VHR is designed for silence and mass-market comfort, not performance. It utilizes restrictive resonator boxes and corrugated plastic tubing that creates immense air turbulence, effectively choking the engine’s throttle response when you try to merge or pass. This restrictive setup forces the engine to work harder to pull air, resulting in a "heavy" feeling during mid-range acceleration and a lack of top-end urgency.

The Engineering Fix: This system replaces that restrictive plastic plumbing with mandrel-bent T304 aluminum tubing. By smoothing out the airflow path and utilizing a high-velocity cone filter, we increase the oxygen density entering the combustion chamber. The included steel heat shield, finished in a durable carbon-black powder coating, acts as a thermal barrier to keep hot under-hood air away from the intake charge, ensuring that the air entering your cylinders is as dense and cool as possible for maximum combustion efficiency.

Why Mechanics Choose This Kit

• Optimized Volumetric Efficiency: By reducing intake restriction, this kit allows for a 7-10% increase in Horsepower and a 6-8% increase in Torque, specifically targeting the VQ’s power band.
• Acoustic Resonance: Removes the factory baffles to provide a deep, aggressive induction roar under load, giving your G37 or Q50 the sporty character it deserves.
• Superior Material Science: Features lightweight T-304 aluminum piping and a washable, reusable high-flow cotton media filter, designed to outlast the vehicle itself.
