Do Performance Air Intakes Make A Difference?

By Daren Foertsch

One of the first modifications when modifying your vehicle is often an aftermarket air intake. They often promise increased horsepower, improved fuel efficiency, and a more satisfying engine sound. But how exactly do aftermarket air intakes deliver these benefits? Let’s break it down.

Cold air intakes are designed to draw cooler, denser air from outside the engine bay. Cooler air contains more oxygen, which allows for better combustion and increased power. These systems often require more complex installations but deliver substantial performance gains. Short ram intakes replace the factory airbox with a shorter, more direct pathway for air. While they may not cool the air as effectively as cold air intakes, they are easier to install and still provide noticeable performance improvements.

Internal combustion engines rely on a precise mix of air and fuel to generate power. The air intake system ensures that clean oxygen reaches the engine; the more efficiently this system works the better the engine performs. Factory air intake systems are designed for reliability and noise reduction, but are often restrictive. Aftermarket air intakes are designed to maximize airflow and improve overall engine performance.

One of the main reasons drivers install aftermarket air intakes is to increase the horsepower. By reducing airflow restriction, it allows the engine to breathe easier. Improved airflow means more air for the combustion process, leading to a boost in power. Depending on the vehicle and intake design, one can expect gains of 5 to 20 additional horsepower. Aftermarket air intakes often improve throttle response, making the vehicle feel more responsive. The reduced restriction in airflow means the engine can react quicker when accelerating, delivering a more immediate response and satisfying driving experience.

While fuel efficiency gains can vary, some drivers report modest improvements. By optimizing the air-to-fuel ratio and reducing engine strain, it can increase efficiency under certain driving conditions, particularly at highway speeds. For many, the improved engine sound is an added bonus. Aftermarket air intakes often amplify the engine’s natural growl, providing a deeper, more aggressive tone.

Installing an aftermarket air intake is a relatively straightforward process, often requiring only basic tools and mechanical knowledge. However, it’s crucial to choose an intake system that’s compatible with your specific vehicle make and model. Additionally, one should be aware of potential warranty implications and ensure the system complies with local emissions regulations. Regular maintenance, including cleaning the air filter, is essential to keep the system functioning optimally.

An aftermarket air intake is a cost-effective way to unlock more of your vehicle’s potential. From increased horsepower and improved throttle response to better engine sound, this simple upgrade can upgrade your experience behind the wheel.
