inlet manifolds

Inlet manifolds, also known as intake manifolds, are components in an engine's air intake system. They are responsible for distributing air (and sometimes fuel in fuel-injected engines) evenly to the engine's cylinders for combustion. The inlet manifold collects air from the air filter and directs it into the cylinders through individual ports or runners. In some designs, the inlet manifold also incorporates a throttle body, which regulates the airflow into the engine. The design of the inlet manifold plays a crucial role in the engine's performance, as it can affect factors such as air/fuel mixture distribution, volumetric efficiency, and overall power output.
