DENSO Iridium Racing Plug IWM01-31

[KITACO 025-022-0310000 DENSO Iridium Racing Spark Plug IWM01-31 KITACO 025-022-0310000]
"Iridium Racing" - A race-specific iridium spark plug that maximizes iridium performance.
●0.8mm square all-platinum ground electrode
Compared to the nickel alloy used for conventional spark plug ground electrodes, platinum has a higher melting point, so
melting or wear of the ground electrode is reduced even under severe racing conditions.
In addition, 0.8mm square platinum alloy is welded and gap-formed without bending, eliminating residual stress and improving durability. *Excluding RU01
●0.4mm diameter ultra-fine iridium center electrode
By adopting "new iridium alloy," a high melting point material, the tip of the center electrode has been made ultra-fine. This reduces spark voltage and significantly improves ignition performance. *Excluding RU01
●Flame cleaning pocket
Small gaps have been created around the entire circumference of the tip of the clearance between the center electrode and the insulator. This burns off carbon when fouled or carbonized, restoring insulation.
●Silicone oil application
For racing vehicles, fouling and carbon buildup before the start are critical. 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 performance.
●Housing end chamfering
To improve resistance to abnormal combustion, the chamfering at the end of the housing has been increased.
This also covers slight setting discrepancies.
In addition, the discharge of residual gas and the influx of new gas are facilitated, improving self-cleaning performance, making it a structure that is less prone to fouling.

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