DENSO DENSO Iridium Racing Plug IWM01-29

【KITACO 025-022-0290000 DENSO Iridium Racing Plug IWM01-29 KITACO 025-022-0290000】
"Iridium Racing," a race-specific iridium plug that maximizes the performance of iridium.
● 0.8mm Square All-Platinum Ground Electrode
Compared to the nickel alloy used for ground electrodes in conventional spark plugs, platinum has a higher melting point, which reduces melting issues and wear of the ground electrode even under the harsh racing conditions.
In addition, a 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 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. *Excluding 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 carbonized, restoring insulation.
● Silicone Oil Application
For racing vehicles, fouling and carbon buildup before the start are fatal. To prevent this,
the water repellency of silicone on the insulator separates moisture and carbon from the surface of the insulator, preventing a decrease in the plug's insulation performance.
● Housing End Face Chamfering
To improve resistance to abnormal combustion, the chamfering of the housing end face has been enlarged.
This helps to cover even slight setting discrepancies.
Furthermore, it facilitates the discharge of residual gas and the inflow of new gas, improving self-cleaning performance and making the structure less prone to fouling.

● Race-Specific Insulator
A new reinforced insulator, developed through countless repetitions of race driving, has been adopted, improving strength by approximately 20% compared to conventional insulators.
