Exhaust Manifold
Cummins®

The Exhaust Manifold (Part Number: 4970227) is a crucial component of a truck's exhaust system. It is responsible for collecting exhaust gases from the engine's cylinders and channeling them to the exhaust pipe. The manifold is located on the side of the engine block and is typically made of cast iron or stainless steel. Its design ensures that all cylinders have equal access to the manifold, which helps to maintain optimal engine performance and reduce emissions. Over time, the manifold can become damaged or develop cracks due to exposure to extreme heat and pressure. If this occurs, it can lead to decreased fuel efficiency, increased emissions, and potential damage to other components in the exhaust system. It is important for truck owners to regularly inspect their exhaust manifold for signs of wear or damage and replace it as needed to ensure optimal performance and compliance with emissions regulations.
