Cheap BMW 8 Series Inlet Manifold

All petrol-engined 8 Series models have an inlet manifold, including the six-cylinder and V8 variants across the G14, G15, and G16 generation (2018 onwards). The M8 and Competition variants also have inlet manifolds as part of their high-performance petrol engines. Diesel variants use a different style of inlet tract, so always confirm with the breaker whether the part they hold suits petrol or diesel when searching.

The current 8 Series range (G14 Convertible, G15 Coupé, G16 Gran Coupé) runs from 2018 through to the end of production, so a 2019 and 2022 car sit within the same generation. However, fitment is driven by engine code rather than year, so a 2019 840i and a 2022 840i sharing the same engine code are far more likely to interchange than two cars from the same year with different engines. Supply your engine code to the breaker and ask them to match it directly rather than relying on year alone.

Trim levels like M Sport, M Sport Pro, or First Edition on the 8 Series are largely cosmetic and equipment packages, so they do not change the engine or its inlet manifold. What matters is which engine is fitted — for instance, a 840i and an 840d of the same year will need completely different inlet manifolds despite sharing a bodyshell. Give the breaker your engine code and fuel type, and trim level can be disregarded entirely for this part.

The M8 and M8 Competition use BMW's S63 V8 engine, while the 840i uses the B58 inline-six and the 850i uses the N63 V8, so these are entirely different engine families with different inlet manifolds. Parts from an M8 will not cross over to a 840i or 850i even though the body is shared. Always identify the exact engine code on your V5 or via a VIN check before approaching a breaker.

The 840d uses a diesel engine (engine code B57) which has its own inlet manifold designed around diesel combustion and forced induction requirements, so it is not interchangeable with any petrol variant. When searching, make sure to specify diesel and supply the B57 engine code to the breaker so they can source the correct part. Some ancillary fittings and EGR connections on diesel manifolds can vary, so ask the breaker to confirm the part matches your specific registration.

The 8 Series G-generation has been in production since 2018 and there have been no widely publicised major mid-cycle engine changes that would split inlet manifold fitment within the same engine code, but minor ancillary or mounting detail changes during a production run are always possible. The engine code remains your most reliable guide, and a breaker can cross-reference your registration against their stock to catch any such variations. Rather than assuming, always ask the breaker to confirm against your reg before purchasing.
