A fuel injector (10, fig 1), for an internal combustion engine, comprising a cartridge provided with a body (12, fig 1) with a bore (16, fig 1), a fuel inlet (18, fig 1) and a fuel outlet (20, fig 1). A needle (14, fig 1) extends from a head (22, fig 1) to a tip (24, fig 1), and reciprocates in the bore along a longitudinal axis from a closed position, in which the tip of the needle closes the fuel outlet, to an open position, in which the tip of the needle is spaced apart from the fuel outlet. A magnetic armature (40, fig 1) is arranged to move along an axis according to a magnetic field, the movement of the armature controlling the reciprocating of the needle in the bore. The fuel injector has a coil (42, fig 2) that generates the magnetic field to control the movement of the magnetic armature. A coil housing (44) comprises an assembly of two joined half shells (46, 48).
