Fuel injector SMART

SMART fuel injector, exchange part: a common rail diesel injector standing upright against a dark grey background

3 exchange-standard references cover 2 SMART models, from the earliest generations to the latest. Let's start with the most ordered: Forfour, Fortwo.

The 3 SMART references in the catalogue are supplied as exchange units, with a 24-month warranty.

Every sheet details the available engines and their outputs: on SMART as elsewhere, two neighbouring body shells can take different parts depending on engine code and production year. If you know the code stamped on your part, search by reference goes straight to it; otherwise, your model below leads to the engines covered.
