Cheap BMW 7 Series Air Filter

Every BMW 7 Series has an air filter regardless of engine — petrol, diesel, or plug-in hybrid — because all internal combustion engines require filtered air intake. Even the 745e and 750e plug-in hybrid models still run a petrol engine alongside the electric motor and need an air filter. The only 7 Series variant with no air filter requirement would be a fully electric model such as the i7, which has no combustion engine at all. If you own an i7, an air filter is not the part you need.

No — the G11 generation (2015–2022) and the F01/F02 generation (2009–2015) use entirely different engines with different air filter housings, so they do not share a filter. Even where engine displacements sound similar across the two generations, the engine codes differ and the filter specification changes accordingly. Always search by engine code rather than by displacement alone when looking for a used air filter from a breaker.

Both the 2010 and 2012 740d sit within the F01 generation (2009–2015), so they are likely to share the same air filter provided the engine code matches. The 740d used the N57 diesel engine throughout that generation, which supports compatibility, but you should confirm the exact engine code from your V5 or a VIN check and supply it to the breaker before buying. Engine code is the single most reliable guide for this part.

No — the wheelbase or body length does not affect the air filter fitment at all. The air filter is determined entirely by the engine, so a standard 730d and a 730Ld with the same engine code will use the same filter. When contacting a breaker, focus on the engine code rather than whether your car is an L model.

Trim level makes no difference to air filter fitment on the 7 Series — SE, Sport, and M Sport versions with the same engine code all use the same filter. Trim affects interior specification and cosmetic details, not the engine or its air intake system. Confirm your engine code from your V5 and pass that to the breaker, and trim is irrelevant to the search.

The G11 received a facelift in 2019, and it is worth flagging your exact year and engine code to the breaker because ancillary or housing details can occasionally change mid-production. The core filter specification follows the engine code, so start there, but for a 2016 pre-facelift car you should confirm against your registration with the breaker to rule out any minor mid-cycle changes. Supplying your engine code alongside the registration gives the breaker the best chance of matching the correct part.
