SKU: 274-0163 Category:


  • ACCEL C-Cut Copper Spark Plugs creates a considerably hotter spark that lets the flame expand more rapidly in the combustion chamber
  • Allows spark to expand directly above the midpoint of the electrode core – preventing the spark from being shrouded by the ground strap
  • Gives the flame an unblocked area to grow – creates a larger flame front for a more complete burn
  • Reduces excess heat absorption of the electrode and ground strap, also known as the “quenching effect”, which leads to misfiring, rough idle and overall poor performance
  • Produces a larger spark nucleus without having to increase the spark gap
  • Creates a more complete burn of the air-fuel mixture resulting in increased performance, improved throttle response, greater fuel efficiency and reduced emissions
