NGK U5019 / 48063 Ignition Coil Genuine NGK ComponentEssentially the operating principle is the same for all types of ignition coils- whether the classic can-type coil, or in a coil rail system. The device contains two copper wire windings and a laminated iron core. The copper wires are insulated to prevent short circuits. The battery current fed through the primary winding produces a magnetic field whose strength is further increased by the iron core. When this circuit is opened, the magnetic field collapses, inducing a high voltage pulse in the secondary coil.U5 Type Ignition CoilNo ignition cables are required The NGK ignition coil of the Type U5 is a pencil coil with single spark technology. One such ignition coil is attached at each cylinder.BOX DIMENSIONSHeight (mm): 65Width (mm): 80Length (mm): 215If you are unsure as to whether this is the correct part for your vehicle, please don’t hesitate to contact us.
