Used BMW 1 Series Inlet Manifold

All petrol-engined BMW 1 Series models have an inlet manifold, as it is a fundamental part of any petrol engine's air intake system. Diesel variants also have an inlet manifold, though the design differs significantly from the petrol units. So regardless of whether your 1 Series is petrol or diesel, you do have this part — but the two fuel types use entirely different manifolds and will not interchange.

Almost certainly not — the E87 (2004–2011) and F20 (2011–2019) are completely different generations with different engine families, mounting arrangements, and intake systems. Even where an engine code appears similar across generations, ancillary and mounting details often changed, so a direct swap across this generation boundary is very unlikely to work without modification. Confirm against your specific registration with the breaker before ordering.

Yes — the 116i and 120i use different engine codes (for example, the N13 and its variants versus the N46 or later B38/B48 family depending on year), and inlet manifolds are engine-specific parts that follow the engine code rather than the badge or trim level. Always quote your engine code to the breaker, which you can find on your V5C or via a VIN check, as this is far more reliable than the model designation alone. Never assume two different engine codes share the same manifold.

Trim level in itself does not determine which inlet manifold fits; what matters is the engine code under the bonnet. An SE and an M Sport 1 Series with the same engine code will use the same inlet manifold, while two cars wearing the same trim badge but fitted with different engines will need different parts. The exception is the M140i (and earlier 125i/135i performance variants), which use distinct turbocharged engine codes and will need manifolds specific to those units — again, the engine code is the definitive guide.

No — body style has no bearing on inlet manifold fitment whatsoever. The manifold is determined entirely by the engine code, fuel type, and to some extent the model year within a generation. Tell the breaker your engine code and registration, not your body style, and they will be able to source the correct part.

The F20 received a facelift in 2015, meaning a car registered in that year could feasibly be either pre-facelift or post-facelift, and engine ancillary parts including intake components can differ across that boundary. The safest approach is to supply your exact registration and engine code to the breaker so they can confirm which manifold matches your specific build. Do not assume a pre-2015 manifold is a guaranteed fit for a 2015 car without that check.
