Cold air intakes are one of the most accessible and effective upgrades for car enthusiasts seeking to enhance their vehicle’s performance and driving experience. For Infiniti’s G37 and other models, a cold air intake offers improved airflow, increased horsepower, and a more pronounced engine sound. In this article, we’ll explore the benefits, considerations, and features of cold air intakes for the Infiniti G37 and other Infiniti models.
What Is a Cold Air Intake?
A cold air intake replaces the factory airbox and intake tubing, allowing cooler and denser air to flow into the engine. Since colder air contains more oxygen, the combustion process becomes more efficient, leading to increased power output and better throttle response.
G37 Cold air intake are often designed with smoother tubing and high-performance air filters to reduce airflow restrictions and ensure maximum efficiency.
Advantages of a G37 Cold Air Intake
Increased Horsepower and Torque:
A cold air intake delivers colder and denser air, improving combustion efficiency, and there is a noticeable increase in power. Gains of 5-15 horsepower are common with a high-quality system.
Improved Throttle Response:
Improved airflow means the engine responds more quickly to throttle inputs, and the G37 feels more responsive and engaging to drive.
Better Engine Sound:
A cold air intake often makes the induction sound of the engine more profound and aggressive during acceleration.
Better Fuel Economy:
Although the primary focus of a cold air intake is performance, it can improve fuel economy under normal driving conditions by optimizing combustion.
Aesthetics
Many cold air intakes have polished aluminum or carbon fiber components that give a sleek look under the hood.
Infiniti Cold Air Intakes for Other Models
The benefits of Infiniti cold air intake extend beyond the G37 to other Infiniti models such as Q50, Q60, and FX35. These luxury-performance vehicles may also reap similar gains in power, responsiveness, and sound.
Applications Across Infiniti Models:
Turbocharged Infiniti models, like Q50 and Q60, benefit from improved airflow, which improves turbo efficiency and reduces lag.
Cold air intakes in naturally aspirated engines, such as those found in the G37 or FX35, allow for more oxygen and smoother airflow for maximum performance.
Factors to Consider When Choosing a Cold Air Intake
Material and Design:
Look for systems made from high-quality materials such as aluminum, carbon fiber, or high-density plastic that will be durable and withstand heat with the best of them.
Filter Quality:
High-performance filters from companies such as K&N or AEM are washable and reusable, providing long-term value and better filtration than a factory filter.
Compatibility:
The intake system must be specifically designed for the Infiniti model and the correct engine configuration to fit it properly and gain maximum value.
Hydro-Lock Prevention:
Some cold air intakes locate the filter further down the engine bay to capture cooler air. If you live in a rainy location, opt for systems that are rain-proof or look into a short ram intake to not hydro-lock.
