An assembly designed to distribute airflow evenly to the cylinders of an internal combustion engine, often constructed by the user from individual components, enhances engine performance by optimizing air intake. These customized configurations can involve modifying existing factory manifolds or fabricating entirely new designs. A common application includes projects where individuals build their own intake system for racing or high-performance vehicles.
Modifying or creating such an intake system can lead to increased horsepower and torque, particularly at specific engine speeds, due to improved airflow characteristics. This approach allows for tailoring the intake system to the specific needs of the engine and intended use, a capability not always available with commercially manufactured options. Historically, individuals have pursued such modifications to overcome limitations in factory designs and to achieve greater performance gains than available through aftermarket options.
