What is the purpose of high-flow cylinder heads?

High-flow cylinder heads are designed to enhance the engine's performance by increasing the volume of air that can enter the combustion chamber. This improvement is crucial for achieving better combustion efficiency and power output. When the airflow is optimized, it allows for a greater amount of fuel and air to mix, which results in a more potent combustion process. This leads to increased horsepower and torque, making the vehicle perform better, especially in high-performance applications.

While high-flow cylinder heads do have indirect effects on other aspects of engine performance, such as potentially improving fuel efficiency and emissions, their primary purpose is to facilitate a higher volume of air intake. This fundamental change is what drives the modification's benefits in power and engine responsiveness.
