NGK U1011 / 48090 Ignition Coil Genuine NGK Component Essentially 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. U1 Type Ignition Coil One ignition coil per vehicle Number of ignition cables corresponds to the number of spark plugs In addition, a cable to the distributor is required. The NGK Type U1 ignition coil supplies the spark plugs with high voltage through a mechanical ignition distributor.
