Fitment

This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.

What it does

Ignition parts create and deliver the spark that lights the fuel in each cylinder. Electrical faults often show up as warning lights, rough running or no-start problems, and the right replacement part clears the cause rather than the symptom.

Installation & tips

  • Set the spark plug gap to your engine spec and do not over-torque plugs in aluminum heads.
  • Plug wires or boots: Old wires and boots crack.
  • Disconnect the battery before you unplug or splice any wiring, and test everything works before you refit trim panels.
