The insulator housing is plated with burnished nickel the same as racing plugs, resulting in high corrosion resistance. (VKA and VKB excluded)
❸ Built-in, Highly Reliable Resistor
All specification types include an embedded, highly reliable, monolithic resistor to eliminate electromagnetic noise interference from all kinds of electronic devices.
❹ Platinum-tipped Ground Electrode
The ground electrode has a platinum tip, from DENSO’s experience with platinum plugs. This greatly moderates electrode wear and insures high durability.
❺ Fine Diameter Ultra-fine Iridium Center Electrode
Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability.
Realizing high ignition performance with a fine diameter electrode.
