Does an Intake Add Horsepower?

Yes, an intake system can add horsepower to your vehicle, though the amount of horsepower gained depends on various factors. Replacing your stock intake with a performance-oriented cold air intake (CAI) or short ram intake can improve engine performance by increasing airflow to the engine, which in turn can enhance combustion efficiency.

How Does an Intake Increase Horsepower?

1. Increased Airflow: The primary function of an upgraded intake is to increase the volume of air entering the engine. More air means more oxygen, which allows for better combustion and more power.
2. Cooler Air Intake (Cold Air Intakes): A cold air intake draws air from outside the engine bay, where the air is cooler. Cooler air is denser, meaning it contains more oxygen, which leads to better combustion and an increase in horsepower.
3. Reduced Restriction: Aftermarket intakes often have larger, smoother pipes and high-flow filters that reduce the restriction in the airflow path. This reduction in restriction allows the engine to breathe more easily, potentially increasing performance.
4. Enhanced Sound: Many performance intakes also give your engine a more aggressive sound, as the intake allows more air to be drawn in. While this doesn’t directly increase horsepower, it can provide a more noticeable engine note, which some drivers find satisfying.

How Much Horsepower Does an Intake Add?

The amount of horsepower added depends on several factors, including the type of intake, the specific vehicle, and other modifications. On average, a cold air intake can add anywhere from 5 to 15 horsepower. This increase is typically seen in engines that already have some performance capabilities, such as sports cars or modified vehicles. For daily drivers, the gains might be on the lower end of the scale.

Other Considerations

1. Other Modifications: While an intake can improve horsepower, the gains are often modest unless combined with other performance modifications, like a performance exhaust system or a tune.
2. Engine Size and Type: The horsepower gains from an intake will be more significant on higher-performance engines or forced induction setups (e.g., turbocharged or supercharged engines).
3. Tuning: After installing a performance intake, tuning your engine might be necessary to optimize the air-fuel ratio, ensuring the engine runs efficiently and reaps the full benefits of the upgrade.

Conclusion

An intake can add horsepower by improving airflow and increasing the amount of oxygen available for combustion. While the gains can be modest (5-15 horsepower), it is an effective and relatively inexpensive way to improve engine performance, especially when combined with other performance modifications. However, the increase in horsepower varies depending on the type of intake, your vehicle’s engine, and any additional modifications.
