The Iridium Difference
Worlds smallest electrode tip at 0.4mm! This produces the hottest, most concentrated spark, while requiring the lowest voltage (5,000 less volts to fire than conventional spark plugs). For maximum performance under the most extreme conditions, this plug is the one! Patented technology, Iridium plugs outperforms any plug today beating OEM and even Platinum plugs. Enjoy more horsepower, faster and easier starts, fewer misfires under heavy loads, plus better fuel efficiency. In addition, iridium plugs last up to 3X longer than factory plugs!
Iridium plugs best demonstrates their performance improvement for your Mitsubishi during acceleration. Iridium plugs have 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 under lean conditions. As a result, acceleration improves in comparison with normal plugs.
Iridium has low voltage requirements and high ignitability, resulting in fewer misfires. The outcome is a dramatic improvement in combustion, therefore increasing engine output. Test results using a motorcycle engine show improved combustion from (see chart). Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110km/h.
The power produced by our 0.4mm dia. Iridium center electrode is unmatched by other plugs. Using a 0.4mm dia. fine center electrode, there is more power compared to 0.8mm and 2.5mm dia. plugs. This is what makes the difference in acceleration and in your lap time.
Improved Fuel Mileage
The superior ignitability from the fine electrode (0.4mm) of Iridium draws out optimal performance from the engine as illustrated. Comparing a standard plug (W20FS-U) with an Iridium (IWF22) on a 2 cycle 50cc engine, fuel consumption improved from 41.74km/L to 43.69km/L (about 5%). Note: Mileage measured using a chassis dynamometer; actual driving results under normal conditions may vary.
The larger the flame-kernel as seen below, the better the ignition of gas. Normally, this can be accomplished by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect. IRIDIUM uses a U-Groove ground electrode to realize a superb ignitability while maintaining spark voltage at low levels.
