Denso Spark Plug Iridium Power
Spark Plug Iridium Power
Iridium Power® best demonstrates its performance improvement during acceleration. The world's smallest center electrode and specially shaped ground electrode deliver maximum spark energy while withstanding temperatures greater than 4000º F. These features combine to achieve higher ignitability and require lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs.
To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.
Features
- Tapered cut, U-Groove ground electrode
- 0.4mm Iridium Tip
- Patented 360-degree laser welding assembly process
At 0.4mm in diameter, the DENSO Iridium Power center electrode tip is the world's smallest. It 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! Because of its patented technology, the Iridium Power plug outperforms any plug today. You'll enjoy more horsepower, faster and easier starts, fewer misfires under heavy loads, plus better fuel efficiency.
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 under lean conditions. As a result, acceleration improves in comparison with normal plugs.
Iridium Power has low required voltage 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 Iridium Power (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.
The superior ignitability from the fine electrode (0.4mm) of Iridium Power draws out much more performance from the engine. Comparing a standard plug (W20FS-U) with an Iridium Power (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.
