Description

The Cummins 4BT 3.9 Exhaust Manifold 3901635 is an essential component of a truck’s engine that collects and directs the exhaust gases from each cylinder to the exhaust system. The manifold is typically constructed of cast iron or stainless steel, and it attaches to the cylinder head(s) using bolts. The number of outlets on the manifold corresponds to the number of cylinders in the engine. Exhaust manifolds can be either “log style” or “header style,” with header-style manifolds being designed for higher-performance applications due to their more efficient flow characteristics. The exhaust manifold needs to be properly sealed and free from cracks, as any leaks can result in decreased engine performance and potentially harmful emissions.
