Choosing the right used Mercedes-Benz B-Class inlet manifold
Used inlet manifolds vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
- State whether it's petrol or diesel
- State the engine code if known

Fitment questions
Does the Mercedes-Benz B-Class have an inlet manifold?
Yes, but only on petrol and diesel internal combustion engine variants — the B-Class has been offered with a range of four-cylinder petrol and diesel engines across its generations, and all of these use an inlet manifold. However, the fully electric B-Class (the B 250 e was a plug-in hybrid, but note there was no fully battery-electric B-Class in mainstream UK sale) still uses an internal combustion engine alongside its electric motor, so an inlet manifold is present on those too. If you are unsure whether your specific variant has one, check your V5 or run a VIN check to confirm the engine type before ordering.
Will an inlet manifold from a W245 B-Class fit a W246 B-Class?
Almost certainly not — the W245 (2005–2011) and W246 (2012–2018, facelift 2014) are entirely different generations with different engine families, so the inlet manifolds are not interchangeable. The engine codes changed substantially between generations, and the inlet manifold is designed around the specific engine architecture. Always match by engine code, not by model generation alone, and confirm with the breaker against your registration.
Does the inlet manifold from a pre-facelift W246 B-Class fit a post-facelift W246?
The W246 was facelifted in 2014, and while many engines carried over, there can be mid-production changes to ancillary components including inlet manifold mounting or specification. If your engine code is identical on both vehicles, fitment is more likely, but you should confirm with the breaker against your registration rather than assume the pre-2014 and post-2014 parts are a straight swap.
Does trim level affect which inlet manifold I need — for example, does a Sport need a different one to an AMG Line?
No — trim level has no bearing on inlet manifold fitment on the B-Class. Sport, SE, AMG Line and Urban are trim designations that affect interior, cosmetics and equipment, not the engine specification. What matters is the engine code, which you will find on your V5 or via a VIN check, and that is what you should give to the breaker when requesting a quote.
I have a B200 CDI — will an inlet manifold from a B180 CDI fit it?
The B200 CDI and B180 CDI may share the same engine family in a given generation but are typically different states of tune, and in some cases the inlet manifold or associated components differ between power outputs. The safest approach is to supply your exact engine code to the breaker rather than going by the badge alone, as the engine code is the definitive guide for mechanical parts like the inlet manifold. Never assume fitment based on badge or fuel type without verifying the engine code matches.
Can I use a petrol B-Class inlet manifold on a diesel B-Class, or vice versa?
No — petrol and diesel inlet manifolds are completely different components and are not interchangeable under any circumstances. Diesel engines use a different intake system architecture, often incorporating a swirl flap mechanism and EGR connections that are absent on petrol versions. Always confirm your fuel type and engine code with the breaker to ensure you are quoted the correct part.
