ACCEL has improved the ignitability of the spark plug in a new design! ACCELhas always utilized unique electrode grounding designs to improve combustionand create a larger spark.Accel 0576S-4 Features:
- 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 fora more complete burn.
- Reduces excess heat absorption of the electrode and ground strap, alsoknown as the ''quenching effect'', which leads to misfiring, rough idle andoverall 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 -Increasedperformance, improved throttle response, greater fuel efficiency and reducedemissions.
