BMW M8 Fuel Injector Replacement Parts

Yes, fuel injectors are genuine components on the BMW M8 – the M8 (F91/F92/F93, produced from 2019 onwards) uses BMW's S63 twin-turbocharged 4.4-litre V8 petrol engine, which uses direct fuel injection and has eight injectors, one per cylinder. Because the M8 is petrol-only, there are no diesel injectors on any variant. You are looking for the right part on the right model.

The BMW M8 (F91/F92/F93 generation) launched in 2019 and has remained in production through this period without a fundamental engine change, so injectors from a 2020 car are likely to be from the same specification as a 2022 car. However, ancillary and connector changes can occur mid-production, so confirm with the breaker against your exact registration and engine code before buying. The engine code stamped on your V5 or obtained via a VIN check is the most reliable detail to give the breaker.

No, body style does not affect fuel injector fitment on the BMW M8 – the Coupe (F92), Convertible (F91), and Gran Coupe (F93) all share the same S63 4.4-litre twin-turbo V8 engine, so the injectors are mechanically the same across all three body styles. Confirm the engine code matches between donor and recipient vehicle, and the body style of the breaker's car is irrelevant to whether the injector will fit yours.

The M8 and M8 Competition share the same S63 V8 engine architecture, and fuel injectors are determined by the engine code rather than the trim designation. In practice the injectors should interchange between standard M8 and M8 Competition variants, but because the Competition receives engine calibration differences, confirm with the breaker that the engine codes match exactly before purchasing. Trim level alone is not a reason to reject a used injector, but the engine code is the detail that matters.

Give the breaker your engine code (found on your V5 logbook or via a VIN check), your vehicle's registration, and the year of manufacture – this combination gives them everything they need to pull the correct injector. The M8's S63 engine is also used in other BMW M models, so a breaker may be able to source a matching injector from a donor car that isn't an M8, provided the engine code matches. Note that injectors may require coding or programming to your vehicle's ECU, so confirm this with your fitting garage or the breaker before purchase, as this is something to factor into your overall cost.

The BMW M8 uses the S63 V8 engine, which is shared across several BMW M models including the M5 (F90) and X5 M/X6 M (F95/F96), which means there is a genuine possibility that injectors from those models could be compatible with your M8. However, specification differences can exist between applications of the same base engine, so you must confirm the exact engine code with the breaker against your registration rather than assuming compatibility on badge alone. This is a legitimate avenue to explore if M8-specific donor cars are scarce, and a knowledgeable breaker will be able to cross-reference the part numbers for you.
