Manifolds

• The word "manifold" is derived from an Old English word meaning many folds, referring to the folding together of the inputs and outputs within the manifold. Both the intake and the exhaust manifold work together to help the engine operate more efficiently.
  
  

Intake Manifold

• An intake manifold is responsible for evenly distributing air or a combustion mixture to each intake port in an engine's cylinder heads. This is important to optimize efficiency and performance.
  
  

Exhaust Manifold

• Exhaust manifolds collect engine exhaust from the engine's cylinders and deliver it through one pipe to the vehicle's exhaust pipe. They are usually made of cast iron or stainless steel. Properly functioning exhaust manifolds help optimize efficiency and performance.
  
  

Functions

• The two manifolds complement each other: the exhaust manifold removes the air that is brought in by the intake manifold. Working together, these two manifolds allow the engine to maximize its performance and efficiency.
