Cheap BMW M8 Inlet Manifold

Yes, the BMW M8 uses a 4.4-litre twin-turbocharged V8 petrol engine (engine code S63), and it does have an inlet manifold — in fact it has two, one per cylinder bank, as is typical for a V8 layout. This is a genuine fitment item available from breakers who dismantle M8s. Make sure you specify which bank (nearside or offside) you need when requesting a quote.

The BMW M8 (F91/F92/F93 generation) ran from 2019 onwards, and all variants within this generation share the S63 engine code, so in principle the inlet manifold is drawn from the same engine family throughout. However, BMW occasionally makes ancillary or mounting changes mid-production, so whether a 2019 unit is a straight swap onto a 2022 car is something you should confirm with the breaker against your specific registration. Supplying your engine code from your V5 or a VIN check is the most reliable way to match the part correctly.

No — body style does not affect inlet manifold fitment on the M8. All three body variants (F92 Coupe, F91 Convertible, F93 Gran Coupe) use the same S63 V8 engine, so the manifolds are drawn from the same engine, not the body. You may find cosmetic differences in surrounding trim panels if the breaker supplies ancillary brackets, but the manifold itself is unaffected by which body style the donor car was.

Gearbox type does not influence inlet manifold fitment — the manifold sits on the engine and has no connection to how drive is transmitted. All production M8s use an 8-speed automatic, so in practice this distinction will not arise when sourcing from a breaker, but it is worth knowing the principle: engine code is what matters here, not the gearbox.

The M8 Competition uses the same S63 engine family as the standard M8, so the inlet manifold comes from the same engine architecture. Output differences between the standard and Competition models are achieved through software and other engine tuning rather than a different manifold design, meaning trim level alone should not determine fitment. That said, confirm the engine codes match between donor and recipient with your breaker, as this is always the safest approach with used mechanical parts.

The S63 engine is used across several BMW M models, and parts do sometimes cross over between them, which is worth knowing when searching for used stock. However, engine management calibration, mounting positions, and ancillary configurations can vary between applications, so you should not assume direct interchangeability — always supply your exact engine code and registration to the breaker and let them verify compatibility before purchasing.
