DENSO Denso Iridium Racing Plug IW01-27

[KITACO 025-021-0270000 DENSO Iridium Racing Plug IW01-27 KITACO 025-021-0270000]
"Iridium Racing," a racing-specific iridium plug that maximizes iridium's performance.
● 0.8mm square all-platinum ground electrode
Compared to the nickel alloy used in conventional spark plug ground electrodes, platinum has a higher melting point, so
even under the harsh driving conditions of racing, problems with melting and wear of the ground electrode are reduced.
In addition, a 0.8mm square platinum alloy is welded, and the gap is formed without bending, eliminating residual stress and improving durability. *Excludes RU01
● 0.4mm diameter ultra-fine iridium center electrode
By adopting the high melting point material "new iridium alloy," the tip of the center electrode has been made ultra-fine. This reduces flashover voltage and significantly improves ignition performance. *Excludes RU01
● Flame cleaning pocket
A small gap has been created all around the tip of the clearance between the center electrode and the insulator. This burns off carbon when the plug is fouled or loaded, restoring insulation.
● Silicone oil application
For racing vehicles, fouling and carbon deposits before starting are fatal. To prevent this,
the water repellency of silicone on the insulator separates moisture and carbon from the insulator surface, preventing a drop in the plug's insulation.
● Housing end face chamfering
To improve resistance to abnormal combustion, the chamfering on the housing end face has been enlarged.
This also helps to cover slight setting deviations.
In addition, it facilitates the discharge of residual gas and the inflow of new gas, improving self-cleaning performance and making it less prone to fouling.

● Racing-specific insulator
A new reinforced insulator, developed through countless race runs, has been adopted, improving strength by approximately 20% compared to conventional insulators.
