Cheap BMW M3 Fuel Injector

Yes, fuel injectors are a real and core component on every BMW M3 generation — all M3s have been petrol engines with port or direct fuel injection depending on the generation, so injectors are always present. The E36 and E46 M3s used port injection, while the E9x S65 V8, F80 S55 twin-turbo inline-six, and G80 S58 twin-turbo inline-six all use direct injection. Always confirm the exact injector type with the breaker because port and direct injection injectors are completely different parts and cannot be swapped.

No — the E46 M3 (2001–2006) used the S54 inline-six with port fuel injection, while the E9x M3 (2007–2013, covering the E90 saloon, E92 coupe, and E93 convertible) used the S65 4.0-litre V8 with direct injection, so these injectors are entirely different parts. The engine codes alone — S54 versus S65 — confirm there is no crossover here. Supply your engine code to the breaker so they can pull the correct unit.

The S65 V8 engine code ran throughout the entire E9x M3 generation from 2007 to 2013 without a fundamental change to the injection system, so injectors from earlier and later E9x cars are generally based on the same specification. However, there were minor production running changes during this period, and you should confirm the exact part number against your registration with the breaker before buying. Never guarantee fitment across any production boundary without that check.

No — the fuel injectors on the F80 M3 (2014–2020) are fed by the S55 twin-turbo inline-six engine, and that engine and its injection system are the same regardless of whether the car has a six-speed manual or seven-speed DCT gearbox. Gearbox type does not affect injector fitment on this model, so focus on confirming the S55 engine code with the breaker rather than the gearbox designation. Trim level — whether Competition or standard — also makes no difference to injector specification.

The Competition Pack and full Competition model on the F80 M3 brought suspension, exhaust, and power output differences, but the core S55 engine architecture and fuel injection system remained the same as the standard car. Injector fitment is dictated by the engine code — S55 — not by the Competition badge, so a used injector from a standard F80 M3 should correspond to the same specification as one from a Competition. Confirm the exact part number with the breaker against your registration to be certain, as there can be sub-variants within a production run.

Unlikely — the G80 M3 (2021–present) uses the S58 twin-turbo inline-six, while the F80 uses the S55 twin-turbo inline-six; these are distinct engine families with different injection systems and injector specifications. The engine code is the definitive guide here, and S58 and S55 injectors should be treated as separate parts. Always provide your engine code and registration to the breaker so they can verify compatibility rather than relying on the shared M3 badge.
