Volvo Exhaust Manifold 20743490

This is an Exhaust Manifold designed for Volvo D12C series engines, commonly used in various Volvo trucks and heavy construction machinery.

The exhaust manifold is a critical engine component responsible for collecting exhaust gases from the engine cylinders and directing them into the turbocharger or exhaust system.

It is engineered to withstand the extreme temperatures and pressure cycles of the engine's exhaust cycle. It ensures efficient gas flow, which is vital for maintaining turbocharger performance and engine efficiency.

Because this part has several superseding or alternate numbers (such as 3155030, 8170973, and 8170972), it is common to see these numbers grouped together in parts catalogs and listings. If you are ordering a replacement, confirm that the casting matches your specific engine’s port configuration.
