looking for 4 injectors for my dCi (53 plate)

[manutdviva]

I've got black smoke coming out from the exhaust and the mechanic said it's probably injectors....now I looking for some second hand injectors to put on the diesel K12/ K9K, anyone got injectors for sale?
thanks Kevin

Renault Clios use the same engine so that could be another option.

or fuel pump?

you tried an injector cleaner to see if its helped? Just an idea before you spend ££££ on new injectors
