Denso 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 2200º C. These features combine to achieve higher ignitability and require a lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs.

Ignitability That's a Cut Above

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 the 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 the required voltage.

Iridium Tipped Centre Electrode

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.

Overall Benefits:

• Required ignition voltage reduced - Great for engine starts in freezing conditions.

• Unsurpassed center electrode durability.

• Improved spark ignition for maximum combustion, even with lean air-fuel mixtures.

• Available for many performance and power sports applications.

• Better MPG
• Improved horsepower
• Smoother engine running with less misfires.
