+ FREE GIFT NGK Ignition Coil KeyringNGK U1076 / 48339 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.U1 Type Ignition CoilOne 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.BOX DIMENSIONSHeight (mm): 100Width (mm): 75Length (mm): 151If you are unsure as to whether this is the correct part for your vehicle, please don\'t hesitate to contact us.
