BMW 8 Series Coil Pack Replacement Parts

Coil packs are ignition components found only on petrol engines, and the BMW 8 Series has always been available exclusively with petrol engines, so yes, coil packs do exist on this model across its variants. The current G15/G14/G16 generation (2018-onwards) uses individual coil-on-plug units, one per cylinder, fitted to engines including the B58 inline-six and S63/N63 V8. If you have a diesel-badged 8 Series you may be thinking of a different model, but no diesel 8 Series was sold in the UK. Always confirm your exact engine code from your V5 or a VIN check before ordering.

Both the 2019 and 2022 840i sit within the same G15 generation (2018-onwards), and both use the B58 3.0-litre inline-six, so the coil packs are very likely to be the same part. However, there can be ancillary or supplier changes within a production run that aren't always well documented, so confirm the exact part number against your registration with the breaker before buying. The engine code stamped on your V5 is the most reliable thing to quote.

No — M Sport is a styling and equipment package on the 8 Series, not a different engine, so the coil pack fitment is determined entirely by the engine code, not the trim level. An M Sport 840i and a standard 840i both run the B58 engine and will use the same coil packs. Trim differences you might notice between cars are cosmetic — different alloys, interior finish, badging — and none of that affects ignition components. Quote your engine code to the breaker and trim level can be ignored for this part.

No — the M850i xDrive uses the N63 or S63 4.4-litre twin-turbocharged V8, which has eight cylinders and therefore eight coil packs, while the 840i uses the B58 inline-six with six coil packs; these are entirely different parts. The engine code is the critical detail here, so check your V5 or run a VIN check and give that code to the breaker. Never assume interchangeability across different engine families just because the generation and body style are the same.

This is something you should raise directly with the breaker rather than assume either way — coil packs themselves are passive components and do not typically require ECU coding, but there can be considerations around associated ignition systems depending on exact vehicle specification. A good breaker who knows the G-series 8 Series will be able to advise based on your specific registration. Always confirm with the breaker before purchasing a used unit.

No — the original BMW 8 Series (E31, 1990–1999) and the current generation (G15 coupe, G14 convertible, G16 gran coupe, 2018-onwards) are completely different cars separated by nearly two decades, and the engines, ignition systems, and coil pack designs are not interchangeable. For an E31 you need to confirm the specific engine code (for example M70 V12 or M60/M62 V8) with the breaker, as those older units have their own fitment considerations. Quote your engine code and year clearly so the breaker can source the correct part.
