DENSO Iridium Racing Plug IW01-32

【KITACO 025-021-0320000 DENSO Iridium Racing Plug IW01-32 KITACO 025-021-0320000】
"Iridium Racing" - a racing-specific iridium plug that maximizes iridium 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.
Even under the severe operating conditions of racing, problems such as melting or 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. *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
Small gaps have been provided around the entire circumference of the tip of the clearance between the center electrode and the insulator. When fouled or carbonized, carbon is burned off to restore insulation.
● Silicone oil application
For racing vehicles, fouling and carbon buildup 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 decrease in the plug's insulation performance.
● Housing end face chamfering
To improve resistance to abnormal combustion, the chamfering on the housing end face has been enlarged.
This also covers slight setting discrepancies.
In addition, it facilitates the discharge of residual gas and the influx of new gas, improving self-cleaning performance, making it less prone to fouling.

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