- - Denso Iridium Power Series
- - Ultra-fine Iridium Center Electrode
Set of 6 Denso Iridium Power Spark Plugs
A Plug that draws out engine evolution with a high-performance spark!Revving Up Plug Performance With 0.4mm!
Features Built-in, Highly Reliable Resistor - All
Iridium Power plugs include a highly reliable, 5,000 ohm monolithic resistor specification to reduce electromagnetic noise that may affect electronic devices (For all plug types)
Highly Corrosion Resistant Burnished Nickel Plating - The insulator housing is plated with burnished nickel the same as racing plugs, resulting in high corrosion resistance
All-around Laser Welding - The Iridium tip is mounted with an all-around laser welding method that insures high reliability even under the most severe driving conditions
Improved Ignitability - To increase ignitability, the important point is to let the flame kernel caused by the spark to grow to a large size. Normally, this can be accomplishing by widening the spark gap, however this causes spark voltage to increase, which has the opposite effect.
Iridium Power uses DENSO's very own U-Groove ground electrode to realize a superb ignitability while maintaining spark voltage at low levels
