This is a MAHLE piston ring set sized for a 72.20mm cylinder bore, supplied as a three-ring-per-cylinder set built to MAHLE OE production tolerances for correct seal, oil control and compression when rebuilding the engine. The 1.33-liter turbocharged four-cylinder engine family it is sized for was co-developed under the Renault-Nissan-Mercedes alliance, so the same ring dimension is cataloged against both the Mercedes and Renault-Dacia model applications that share this architecture.
Fitment: Mercedes-Benz A-Class, CLA and GLA, chassis W177, C118 and H247, fitted with the M282.914 turbocharged engine (72.20mm bore, matching this ring set).
