ACCEL High Performance Copper Core Spark Plug Elevate ignition efficiency with the ACCEL High Performance Copper Core Spark Plug. Engineered for hotter, more focused sparks, these plugs deliver faster flame propagation, a larger flame front and a more complete burn of the air-fuel mixture. Key Benefits Hotter, concentrated spark: C-Cut copper core produces a stronger spark that expands rapidly in the combustion chamber. Optimal spark placement: Spark expands above the electrode core to avoid shrouding by the ground strap for consistent ignition. Reduced quenching: Minimizes heat absorption by the electrode and ground strap to lower misfires, rough idle and performance loss. Enhanced combustion: Larger spark nucleus and unblocked flame growth create a more complete burn without increasing gap size. Improved performance: Better throttle response, increased fuel efficiency and reduced emissions. Application: Ideal for street and performance engines where reliable, efficient ignition and improved combustion are critical. Why choose ACCEL: Precision copper-core design and C-Cut electrode geometry combine to maximize spark energy and combustion consistency for smoother, more efficient engine operation.
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
