BMW X4 Intercooler Replacement Parts

Yes, but only on the turbocharged petrol and diesel engines — which in practice means every engine the X4 has ever been sold with in the UK, since BMW never offered a naturally aspirated variant in this model. The intercooler cools the compressed charge air before it enters the engine, and all X4 engines use forced induction, so every X4 on UK roads will have one. If you are unsure whether your specific engine has one, your V5 engine code or a VIN check will confirm it.

Almost certainly not — the F26 is the first-generation X4, built from 2014 to 2018, while the G02 is the second-generation model launched in 2018, and the two generations use entirely different engine families with different intercooler sizes and mountings. Even where engine codes look superficially similar across the two generations, the cooling system architecture changed, so cross-generation fitment is very unlikely. Always give the breaker your full engine code, which you will find on your V5 or via a VIN check, so they can match the correct unit.

Trim level does not affect intercooler fitment on the X4 — xLine, M Sport, M Sport X, and base Sport trims all use the same intercooler for a given engine code. What matters is the engine code, not the badge on the tailgate, so a used intercooler from an xLine will fit an M Sport if the engine codes match. Do bear in mind that cosmetic parts around the engine bay may differ between trims, but the intercooler itself is determined purely by the engine.

These two cars belong to different generations — the 2017 car is a first-generation F26, and the 2019 car is a second-generation G02 — so the intercoolers are not interchangeable between them. Within each generation there are also different engine options, so even matching the generation is not enough on its own; you need to match the engine code. Supply your engine code to the breaker and confirm fitment against your registration before purchasing.

The intercooler is driven by engine specification rather than the drivetrain layout, so xDrive four-wheel drive versus rear-wheel-drive configuration does not in itself change the intercooler. What you need to match is the engine code for your 20d variant, since the 2.0-litre diesel has appeared in different states of tune across the F26 and G02 generations with potentially different intercooler specifications. Give the breaker your engine code alongside the registration so they can confirm the correct match.

The second-generation G02 X4 received a facelift for the 2021 model year, bringing styling updates and some engine and equipment changes. Whether the intercooler changed at that facelift boundary for your specific engine is something you should confirm with the breaker against your registration and engine code, as ancillary and mounting details can change mid-production without a major generation change. Supplying your engine code gives the breaker everything they need to check whether a pre-facelift or post-facelift unit is the right fit for your car.
