Used BMW X4 Exhaust Manifold

No – the F26 (2014–2018) and G02 (2018-onwards) are completely different generations built on different platforms, with different engine families, so the exhaust manifolds are not interchangeable across that boundary. Even where engine codes appear similar, ancillary fittings, sensor positions and routing differ between generations. Always confirm against your exact registration and engine code with the breaker before ordering.

Both years fall within the F26 generation (2014–2018), so there is a reasonable chance of compatibility if the engine codes match – the manifold follows the engine, not the model year. However, the F26 received a facelift in 2017 which brought some minor engine revisions, so confirm your specific engine code (for example N20, N26, N47, N57) with the breaker against your registration before committing.

Yes, all BMW X4 variants have an exhaust manifold – it is the cast or tubular component that collects exhaust gases from the cylinder head and routes them downstream toward the catalytic converter and the rest of the system. Both the petrol and diesel engines fitted to the X4 across the F26 and G02 generations use a manifold, so this is a genuine part for this model.

Yes, it matters significantly – petrol and diesel engines have entirely different exhaust manifolds, and the two are not interchangeable under any circumstances. Within each fuel type, the specific engine code (for example N20 or B48 for petrol, N47 or B47 for diesel) determines the correct manifold, so give the breaker your engine code along with your registration to ensure the right part is sourced.

Trim level alone does not affect exhaust manifold fitment – what matters is the engine code and emissions era, not whether the car is badged xLine or M Sport. The exception worth noting is the M40i and M40d performance variants, which use higher-output versions of the engine and may have a different manifold specification, so if your car is an M40i or M40d confirm this specifically with the breaker. Cosmetic differences such as exhaust finisher style are separate from the manifold itself.

The emissions era can affect fitment because Euro 6 engines often have different sensor bosses, EGR connections or integrated catalyst arrangements compared with Euro 5 units, even within the same engine family. The F26 generation spans the Euro 5-to-Euro 6 transition, so a manifold from an earlier car may not match the ports or sensor positions on a later one. Anything involving catalytic converter integration or DPF-adjacent components is strong confirm-with-breaker territory – provide your registration, engine code and build date so the breaker can check the exact specification.
