Mercedes-Benz GLA Inlet Manifold Replacement Parts

Yes, all petrol and diesel variants of the GLA have an inlet manifold — it is a standard component on any internal combustion engine, directing the air-fuel mixture (petrol) or air charge (diesel) into the cylinder head. Every GLA from the first generation (X156, 2013 onwards) through to the current second generation (X247, 2020 onwards) is fitted with one. The exact design varies significantly between engine families, so the engine code is the key detail when sourcing a used one.

Both years sit within the first-generation GLA (X156, 2013–2019), so the generation boundary is not the issue here — what matters is whether both cars share the same engine code, which you will find on your V5C or via a VIN check. If the engine codes match (for example, both are M270 2.0 petrol or OM651 2.1 diesel), fitment is far more likely, but ancillary mounting points and sensor ports can change mid-production, so confirm the exact part number with the breaker against your registration before buying.

The X156 and X247 are distinct generations with different engine families — the X247 moved to newer units such as the M260 petrol — so an inlet manifold from an X156 is very unlikely to be compatible with an X247 even if the displacement looks similar on paper. Always supply both the engine code and registration to the breaker so they can cross-reference the part; do not assume compatibility across this generation boundary.

Trim and badge level do not determine inlet manifold fitment — the engine code does. A GLA 200 and a GLA 250 petrol may look similar but typically run different engine variants (such as M270 in different states of tune), which can mean different manifold specifications, while the GLA 35 AMG uses its own distinct engine code (M260 in the X247 generation). Give the breaker your engine code rather than just the badge name and they will be able to match the correct part.

Yes, fuel type matters enormously — a petrol inlet manifold and a diesel inlet manifold are completely different components and are not interchangeable under any circumstances. Diesel GLA variants (such as those carrying the OM607 or OM651 engine codes) have manifolds designed around a different combustion process and air management system compared to petrol units like the M270 or M260. Always confirm your fuel type and full engine code with the breaker.

Mercedes-Benz does share engine families across models, so a 220d GLA and a 220d A-Class or C-Class of the same era may well use the same base engine code, making cross-model fitment a genuine possibility worth exploring. However, ancillary fittings, sensor positions, and mounting brackets can differ between vehicle applications even with the same core engine, so this must be confirmed by the breaker against both registrations rather than assumed. Providing your exact engine code alongside your registration gives the breaker the best chance of finding a compatible unit from a wider pool of donor vehicles.
