NGK U6011 / 48045 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.U6 Type Ignition CoilNormally, no ignition cables are required NGK ignition coils of the Type U6 are complete systems in which multiple ignition coils for each individual cylinder are comprised in a complete system.BOX DIMENSIONSHeight (mm): 105Width (mm): 390Length (mm): 175If you are unsure as to whether this is the correct part for your vehicle, please don’t hesitate to contact us.
