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.
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.
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.
