BMW 4 Series Intercooler Replacement Parts

No – only the turbocharged engines fitted to the 4 Series have an intercooler; naturally aspirated petrol engines do not use one. In practice, the vast majority of 4 Series models sold in the UK are turbocharged (the common N20, N26, B48, N47, B47, N57, B57 and S55/S58 units all use intercoolers), so most buyers will find their car does have one. If you are unsure whether your engine is turbocharged, check your V5 engine code or run a VIN check before searching.

The F3x generation covers the F32 coupé, F33 convertible and F36 Gran Coupé, all built from 2013 to 2020 with a facelift in 2017, and they share the same engine family across body styles. Body style does not affect intercooler fitment – what matters is the engine code, so an intercooler from an F32 with the same engine code as your F33 or F36 is the right starting point. Always quote your engine code to the breaker to confirm the specific unit and any bracket differences, and never rely on body style alone.

The F3x facelift arrived for the 2017 model year and in some cases brought revised engine variants, so whether a pre-facelift intercooler crosses that boundary depends on whether both cars share the same engine code. Name the boundary to your breaker – if both cars have, for example, the B47 diesel or B48 petrol, fitment may well carry over, but ancillary brackets and pipework can change mid-production. Confirm fitment against your specific registration with the breaker rather than assuming year-to-year compatibility across the 2017 facelift cut-off.

Trim level – whether Sport, M Sport or any other badge – does not affect the intercooler itself; the part follows the engine code, not the trim. xDrive (four-wheel drive) and rear-wheel-drive cars with the same engine code generally use the same intercooler core, though pipework routing can differ, so mention your drivetrain layout to the breaker. The most important details to supply are your engine code, fuel type and year, not the trim name.

Yes, the G22 is a completely new generation launched in 2020 and is not related to the F3x platform, so intercooler parts do not cross between generations. The G22 uses newer engine families such as the B48 petrol and B57 diesel in updated states of tune, with different packaging and pipework compared with equivalent F3x engines. Always buy generation-specific: confirm your engine code and model year with the breaker before ordering.

The single most useful detail is your engine code, found on your V5 logbook or via a VIN check – this tells the breaker exactly which unit your car was built with, far more reliably than the badge or trim level. Also provide your fuel type (petrol or diesel), gearbox type (manual or automatic), whether your car is rear-wheel drive or xDrive, and the model year. With those details a good breaker can cross-reference their stock accurately and flag any known ancillary or pipework differences before the part is dispatched.
