Product details
This Anamoparts piston ring set is offered for Mercedes-Benz M274.910 1.6 L and M274.920 2.0 L turbo petrol engines. It is advertised in STD size for a bore of 83.00 mm, with heights of 1.2, 1.0 and 2.0 mm. The images show four groups of rings; no piston is shown as a sold part.
Read the three dimensions in the correct order
The supplier indicates 1.2 mm for the first ring, 1.0 mm for the second and 2.0 mm for the oil scraper. This order must be maintained when comparing with the piston grooves. These values describe the advertised heights, not the end gap.
The 83.00 mm diameter is given as the nominal bore. The rings appear open in the photos: their free diameter does not constitute a measurement to validate installation in the cylinder.
Advertised dimensional characteristics Point Value Size STD 0.00 Nominal bore 83.00 mm First ring 1.2 mm height Second ring 1.0 mm height Oil scraper 2.0 mm height Engines listed M274.910 / M274.920 Identify the engine beyond the C180 or C200 badge
The supplier table lists several C-Class, E-Class, GLC and GLK models. The names C180 or C200 are not sufficient to determine the engine and the ring reference. Check the VIN, the full code and the piston dimensions.
The references cited are 2740371401, 2740301617, 2740301517, 2740300417 and 2740300817. A common list may bring together different component references; their presence does not prove interchangeability of all assemblies.
Supplier application examples Family Versions and periods cited C-Class C180 1.6 T; C200/C250/C300 2.0 T, depending on W204/W205 version E-Class E200/E250/E260 2.0 T, 2013–2018 GLC X253 GLC200/250/260/300 2.0 T, 2015–2018 GLK X204 GLK200/250 2.0 T, 2013–2015 Prepare the choice for a rebuild
The five photos show four groups of rings of different colours and profiles. They allow the rings to be distinguished, without providing a detailed inventory of each scraper element or proof of surface treatment. Confirm the complete quantity for the four cylinders.
Before ordering, have the cylinder wear and piston grooves checked, as well as any previous re-boring. A standard size does not automatically fit a machined block. The orientation, clearances and installation checks must be those of the engine and the rings received; no universal clearance value is given here.

Frequently asked questions
What bore size is advertised?
The supplier states a nominal bore of 83.00 mm in STD dimension 0.00. This value must be verified against the condition of the engine block.
What are the segment heights?
The announced order is 1.2 mm for the first, 1.0 mm for the second, and 2.0 mm for the scraper. These are not cutting clearances.
Are the pistons included?
This offer covers piston rings. The photos show four sets of piston rings, without pistons included in the kit.
Are the 1.6 and 2.0 L motors all compatible?
No. The source cites M274.910 and M274.920; the exact code, VIN, references, and dimensions must match.
Does the kit fit a reamed block?
The only stated rating is STD. Adaptation after re-boring cannot be confirmed without measurements and the corresponding repair dimension.
