Pro Tips:

  • Check Spark plug gap! Never install a spark plug without first checking gap and carefully adjusting if necessary. (these plugs are NOT pre-gapped)
  • Supercharged vehicle - Use .032 gap.
  • Non-supercharged vehicle - Use factory specified gap. (see fsm)
  • Iridium spark plugs have a delicate Iridium electrode. When gapping use high quality gapping tools and feeler gauges. If using a traditional plug gapper avoid contact with the Iridium electrode at all times. Manipulate the plug's ground strap only!
  • Inspect plugs for hairline cracks and damage before installation. Plugs can be mishandled, dropped and damaged. Carefully inspect a plug's electrode, porcelain and ceramic portion. 
  • Apply Anti-seize compound to spark plug threads.
  • Apply dielectric grease to coil pack/spark plug wire boot.
  • Always tighten to manufacturer's recommended torque spec. 
  • Read your old spark plugs; Reading an older plug removed from an engine can play a crucial roll in engine health!
  • Check old Gap!: Checking gap on a old plug that's been removed is commonly overlooked! Recording gap size on a used plug will help the user determine how often plugs should be serviced. As plugs wear the gap will increase in size. 
  • Coloration: The color of the insulator nose and electrodes can indicate if a engine is operating smoothly or requires some adjustments. 
    Deposits: Examining deposits on the spark plug can reveal information about the fuel and oil consumption.
