IRIDIUM POWER ®
0.4mm Iridium Center Electrode Delivers Maximum Spark Energy
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.
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
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
• Worlds smallest 0.4mm iridium center
electrode
• Patented 360-degree laser welding

Ground Electrode
Benefits:
• Required ignition voltage reduced
• Unsurpassed center electrode durability
• Available for many performance and power sports applications, including Corvette, Viper, and Harley-Davidson
• Improved spark ignition for maximum combustion, even with lean air-fuel mixtures
Twin-Tip Design Proves Two Tips are Better Than One!
The Platinum TT® concept originated from DENSO's latest original equipment spark plug technology, the
Super Ignition Plug (SIP). Until recently, this OE iridium Twin-Tip design could only be found in the most
technologically advanced automobiles. But now DENSO is offering this cutting-edge technology in a brand
new platinum/titanium design customized for today's value-minded automotive enthusiasts.
A Pioneer in Platinum
DENSO pioneered the use of platinum in spark plug manufacturing. To maximize the longevity and
enhance the durability of the spark plug, DENSO applied platinum to both the center and ground
electrodes. Platinum offers superior resistance to erosion and corrosion enabling DENSO to create a spark
plug capable of consistent performance.
