Part Details

  • Quantity:   8 Piece Set

The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time and cause a misfire condition. In engines like this that use a coil, if the coil goes bad, the complete assembly needs to be replaced.

This Ignition Coil SET features the following specifications:

  • SET contains 8 coils. Enough for one 8 cylinder engine
  • New not remanufactured
  • Replaces dealer part numbers: 22448-AR215, 22448AR215

Note: For vehicles requiring Engine ID (Identification): The Engine ID is usually located on a paper tag located on the valve cover.
