High Performance Copper Core Spark Plug
- 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
