Unbeatable acceleration performance on the circuit.
With 0.4 mm diameter center electrode, IRIDIUM RACING plugs are the realization of superb ignition performance and spark voltage at unparalleled levels. Misfires have been controlled and will allow you to have steadily high levels of response and increased acceleration.
Improved Horse Power
More power with an ideal combustion cycle.
Through superb ignition performance and spark voltage, non-firing and misfires under a variety of conditions has been greatly reduced. As a result, combustion conditions have improved dramatically, increasing engine output.
