BMW M8 Throttle Body Replacement Parts

Yes, the BMW M8 uses a high-performance twin-turbocharged 4.4-litre V8 petrol engine (S63 family), and like all modern petrol engines it does have a throttle body controlling airflow into the intake system. It is not a part unique to one variant — all M8 models share this petrol V8, so every M8 produced has one. If you were searching for a throttle body on a diesel model, the M8 was never offered with a diesel engine, so you may be thinking of a different BMW model entirely.

The BMW M8 (F91/F92/F93 generation) was launched in 2019 and has run through to the current production period without a fundamental engine architecture change, so early and later cars share the same S63 V8 family. That said, ancillary components and mounting details can change quietly during a production run, so you should confirm with the breaker by providing your exact engine code — found on your V5 or via a VIN check — rather than relying on model year alone. Engine code matching is the single most reliable way to ensure the part will suit your car.

No — body style makes no difference to throttle body fitment on the M8. All three bodystyles (Coupe, Convertible, and Gran Coupe) use the same S63 4.4-litre twin-turbo V8, so the throttle body is mechanically identical across them. Focus on matching the engine code rather than the body style when speaking to a breaker.

The standard M8 and M8 Competition both use variants of the S63 V8, though the Competition produces more power through ECU tuning and some hardware differences rather than a fundamentally different intake setup. Whether any throttle body differences exist between the two variants is something you should confirm with the breaker against your specific engine code and registration, as subtle component changes are possible. Providing your engine code from the V5 or a VIN check is the safest approach.

The BMW M5 (F90 generation) also uses the S63 4.4-litre twin-turbo V8, which is the same engine family as the M8, so there is a genuine possibility of compatibility. However, ancillary specifications and mounting details can vary between different vehicle applications of the same engine, so you must confirm with the breaker by comparing the exact engine codes from both donor and recipient vehicles before purchasing. Never assume fitment based on shared engine family alone.

Whether a used throttle body requires ECU pairing or any coding to your specific vehicle is something you must confirm with a BMW specialist or the breaker, as this falls into immobiliser and ECU adaptation territory that varies by build and software version. It is not something that can be stated as fact here, and getting it wrong could affect how the engine runs. Ask the breaker and your fitting garage before purchasing a used unit.
