More Spark = More Power
These ACCEL silver tip racing spark plugs have better ignitability than conventional performance spark plugs and offer better performance and reliability in high-boost nitrous or high-compression engines. Silver is the element with the most free electrons and is the best electrical and thermal conductor of all metals.
Resistant to Fouling
The ACCEL silver tip racing spark plugs have a fine-wire center electrode which gives more room for the insulator between the center electrode and spark plug shell. More insulation results in more durable spark plugs with high dielectric strength. They provide a powerful spark improved performance low ignition requirements excellent heat dissipation at full load and supreme anti-fouling resistance under light load operation.
