These NGK Ignition Coils, also known as engine coils or spark plug coils, deliver the highest in durability and operational performance. Manufactured to OE standards, NGK Spark Plug Coils take power from the alternator and relay that power to the spark plugs. This ignites the fuel and makes your vehicle run. While ignition coils are built to last, over time, your current ignition coil may have begun to fail. With this in mind, if your vehicle exhibits bad ignition coil symptoms including backfiring, misfiring, stalling, or not starting in cold weather, consider NGK, the ignition ...

   Quantity: Set of 4 Kits. The Ignition Coil is located near the distributor in older applications, on top of the ignition control module in distributor-less ignition systems or as a coil-on-plug or coil-near-plug in. For What: The Ignition Coil supplies the needed voltage required to fire the spark plug and complete the ignition cycle. The secondary output voltage from the ignition coil is generated when the voltage in the ignition coil primary circuit is momentarily shorted to ground and then open circuited. The magnetic field within the coil collapses when the circuit opens inducing ...
