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)
• 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.
