- The exhaust manifold in a Jeep is located down to the sides of the engine below the valve covers. A heat
shield covers them and the spark plugs are cradled by them
- The exhaust manifold is tasked with collecting the exhaust fumes generated by an internal combustion engine and conveying them towards the catalytic converter or turbocharger.
- Exhaust manifolds are often made of alloyed cast iron, which is able to withstand the high exhaust temperatures.
- Exhaust manifolds are subject to high thermal stress because they are the first component to convey exhaust fumes away from the engine.
- The design of the exhaust manifold has a significant influence on the performance and torque characteristics of an engine, as does the design of the connected pipes.
