Introduction:
The passages in the cylinder head leading to or from the valves are called ports. The system of pipes, which connect the inrake ports of various engines, is called the inlet manifold.If the exhaust ports are similarly connected to a common exhaust system, then this system of piping is called exhaust manifold.
