Used Mercedes-Benz SLK Inlet Manifold

Yes, all variants of the SLK have an inlet manifold — it is a fundamental engine component present on both petrol and diesel engines, and the SLK was offered with a range of petrol engines across its three generations, all of which use one. Whether your SLK is naturally aspirated or supercharged/turbocharged, the inlet manifold is there, though its design and configuration will differ significantly between engine types.

Almost certainly not — the R170 ran from 1996 to 2004 and the R171 from 2004 to 2011, and while there is some engine family overlap, the engine mountings, manifold geometry, and ancillary connections changed substantially between generations. Your engine code (found on your V5 or via a VIN check) is the most reliable guide here, and you should confirm cross-generation compatibility directly with the breaker against your registration before ordering.

Trim level — whether your SLK is a standard, Kompressor, AMG Sport, or Final Edition — does not determine inlet manifold fitment; what matters is the engine code, which is the single most useful detail you can give a breaker. Two SLKs with identical engine codes will need the same manifold regardless of trim name or interior specification. Check your engine code on your V5 or ask for a VIN check, and supply that to the breaker rather than just the trim badge.

Both years fall within the R171 generation (2004–2011), so there is a reasonable chance of compatibility if the engine codes match, but ancillary connection points and sensor positions can change mid-production within a generation. Confirm the specific engine code on both vehicles and check with the breaker against your registration to be sure before purchasing.

Yes, fuel type matters a great deal — the SLK range in the UK was predominantly petrol, and manifold design differs between petrol and diesel engines in terms of porting, sensor bosses, and EGR connections. Always tell the breaker your fuel type alongside your engine code, as these two details together will narrow down compatibility far more accurately than year or model badge alone.

Unlikely — the Kompressor engines use a forced-induction setup that alters the airflow path and manifold design compared with the naturally aspirated version of a similarly badged engine, so the two manifolds are generally not interchangeable. The engine codes will typically differ between these variants, so supply your exact engine code to the breaker who can confirm whether the part from a donor vehicle matches yours.
