Improved Horse Power
Get more power with an optimal combustion cycle.
IRIDIUM POWER has a low required voltage and a high ignitability, resulting in less misfiring and no spark, the outcome being a dramatic improvement in combustion. Engine output is thus increased. The findings of a bench test using a motorcycle engine to show the improved combustion from IRIDIUM POWER is shown on the below. Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110km/h.

Improved Acceleration
Increased response and acceleration performance.
IRIDIUM POWER best demonstrates its performance improvement during acceleration.IRIDIUM POWER has a 0.4 mm diameter iridium center electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.diagram
Improved Fuel Economy
Even during idling ignition is assured, with less fuel consumption and less noise.
The good ignitability from the fine electrode (0.4mm) of IRIDIUM POWER draws out much more performance from the engine. Comparing a normal plug (W20FS-U) with an IRIDIUM POWER(IWF22) on a 2 cycle 50cc engine, fuel consumption improved from 41.74km/L -> 43.69km/L, an improvement of about 5%.
Note: Mileage measured using a chassis dynamo; actual driving results under normal conditions may vary.
