Second Hand BMW M8 Camshaft

Yes, every variant of the BMW M8 uses a twin-turbocharged 4.4-litre V8 petrol engine (S63 family), and like all internal combustion engines it has camshafts — in fact the S63 uses a twin-cam (DOHC) layout per cylinder bank, giving four camshafts in total. This is not a hybrid-only or electric model, so there is no variant without a camshaft. When searching, be aware that you need to specify which of the four camshaft positions you require (inlet or exhaust, NS or OS bank).

The BMW M8 (F91/F92/F93) was produced from 2019 onwards as a single generation, with a mild facelift introduced for the 2022 model year — the core S63 engine architecture was carried across, but ancillary and mounting details can change mid-production, so you should confirm exact interchange against your registration with the breaker. The engine code from your V5 or a VIN check is the single most useful detail to supply, as it will confirm which exact specification of S63 unit your car uses. Never assume a part fits on year alone.

No, trim level does not affect camshaft fitment here; both the standard M8 and the M8 Competition use the same S63 V8 engine family, and the Competition's power increase comes from software and tune rather than a different camshaft profile in most cases. What actually matters is the precise engine code, fuel type (all M8s are petrol), and the camshaft position you need (inlet or exhaust, and which bank). Confirm the engine code with the breaker to be sure, but trim alone should not be a barrier.

No, body style does not affect camshaft fitment; the Gran Coupe (F93) shares the same S63 V8 engine as the Coupe (F92) and Convertible (F91). Camshafts follow the engine, not the body, so the part you need is determined by your engine code and the camshaft position required. Supply your full VIN or engine code to the breaker and they can match the correct part regardless of which body style it came from.

The M8 uses the high-performance S63 engine, which is a distinct unit from the N63 V8 found in standard 8 Series (840i is actually a six-cylinder; the 850i uses the N63) and other non-M models — these are not the same engine and their camshafts are not directly interchangeable. Always match the engine code exactly: S63 camshafts are specific to M-division applications. A breaker will be able to confirm compatibility if you supply your engine code, but do not assume an N63 part will suit an S63.

A camshaft is a mechanical part and does not require electronic pairing in the way a DME or fuel injector might, so coding is not typically a concern for the camshaft itself. However, if the job involves disturbing sensors such as the camshaft position sensor or associated variable valve timing (Valvetronic/VANOS) components, you should confirm with your fitting garage whether any ancillary parts need attention. For anything related to ECU pairing or immobiliser implications of associated parts, confirm with the breaker and your garage against your specific registration.
