NGK U3004 / 48024 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.U3 Type Ignition CoilThe number of ignition cables corresponds to the number of spark plugs. The NGK ignition coil of the Type U3 is a block ignition coil with two high-voltage outlets. It simultaneously supplies two spark plugs with high voltage through one ignition cable each (double spark technology).BOX DIMENSIONSHeight (mm): 62Width (mm): 130Length (mm): 110If you are unsure as to whether this is the correct part for your vehicle, please don’t hesitate to contact us.
