BENEFITS and FEATURES OF THE IRIDIUM POWER PLUG:

DENSO has thoroughly evaluated the properties required for plugs, and this has been reflected in the IRIDIUM POWER design specifications. These properties are operational stability, acceleration, starting, durability, fouling resistance.

In all respects, IRIDIUM POWER performs better than electrodes with diameter 0.6mm and above. DENSO's own patented new iridium alloy is what made this possible. DENSO seeks not only to be balanced, but to be the best in all respects.

THE SECRET BEHIND DENSO's IRIDIUM PATENT!!

Plug electrodes conventionally have used nickel and platinum. These are not pure metals, but alloys containing other metals. Depending on the composition of the alloy, the matrix material's properties can be maximized. Using the same approach, iridium is alloyed with rhodium. The rhodium layer covers the iridium, improving the properties of the iridium. The iridium/rhodium technology was recognized by the Patent Offices of JAPAN & UK, and in January 1999, a patent was granted in each respective country. Because of the technology, DENSO was able to reduce the electrode diameter down to 0.4mm, thus improving ignitability and sparkability, the benchmark of plug performance.

BENEFITS OF THE IRIDIUM POWER PLUG:


A.
Increased Oxidation Corrosion Resistance with Iridium Alloy!

A 0.6mm diameter pure iridium electrode has a thick diameter, but oxidation corrosion occurs on a part of electrode, and with constant usage, the electrode will fall off. However, DENSO's new 0.4mm diameter iridium alloy (optimized for plug electrodes) displays a high degree of oxidation corrosion resistance.

B. More Output with an Improved Combustion!

IRIDIUM POWER has a low required voltage and a high ignitability, resulting in less misfiring and no sparking, the outcome being a dramatic improvement in combustion. Engine output is thus increased.

C.Increased Ignitability gives Higher Acceleration!

The difference in performance with IRIDIUM POWER is most apparent in the acceleration. With a 0.4mm diameter center electrode and specially shaped ground electrodes, IRIDIUM POWER gives high ignitability and low required voltages. This results in fewer non-firing and misfiring under high voltage and difficult ignition conditions. Acceleration improves when compared with normal plugs.

D. Less voltage required

IRIDIUM POWER spark plugs require on average 5,000 fewer volts to fire than conventional platinium spark plugs, according to the SAE Technical Paper Series (March 1-4, 1999).

Less power is required to fire IRIDIUM POWER Plugs, and coupled with our patented U-Groove technology, the use of Iridium alloy, the tapered cut, and the ultra fine 0.4mm diameter electrode translates to increased horsepower throughout the dyno range.
