M2734.7L / 5.5L Petrol Engine for Sale
Used Mercedes M273 petrol engines for sale from our Centurion yard, fitting 11 Mercedes chassis. The M273 is the V8 sibling of the M272, produced from 2005 to 2013 in 4.7L and 5.5L variants. It shares the same idler/sprocket wear issue as its V6 cousin, but is otherwise a robust luxury V8 that powered the bulk of S-Class, GL-Class, SL-Class and G-Class non-AMG models for the better part of a decade.
