It refers to the intake pipe between the carburetor or throttle body and the intake port of the cylinder head. Below are the specific details about the relevant content: Introduction to intake manifold: For carburetor or throttle body fuel injection engines, the intake manifold refers to the intake pipe between the carburetor or throttle body and the intake port of the cylinder head. Function: It distributes the air-fuel mixture from the carburetor or throttle body to the intake ports of each cylinder. The intake manifold must distribute the air-fuel mixture or clean air as evenly as possible to each cylinder. To achieve this, the length of the gas flow channels inside the intake manifold should be as equal as possible. To reduce gas flow resistance and improve intake efficiency, the inner walls of the intake manifold should be as smooth as possible.
