Spark Plugs: Installation

  1. Installation is a reversal of the removal procedure.
    • Check electrode gap is to the correct specification. Refer to the SPECIFICATION  and/or any applicable TSB(s).
    • Apply suitable lubricant e.g. Neverseez Compound, to lower four threads of spark plug(s) adjacent to the electrodes.
    • The lubricant must be applied to full thread depth for at least 180° of the thread circumference.
    • The electrodes must not be contaminated during this process.
