DENSO Denso Iridium Racing Spark Plugs IWM01-34

【KITACO 025-022-0340000 DENSO Iridium Racing Plug IWM01-34 KITACO 025-022-0340000】
"Iridium Racing," an iridium plug for racing that maximizes the performance of iridium.
● 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,
This reduces issues such as melting and wear of the ground electrode, even under the harsh driving conditions of racing.
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
A small gap has been provided all around the tip of the clearance between the center electrode and the insulator. This burns off carbon when sooty or fouled, restoring insulation.
● Silicone oil application
For racing vehicles, fouling and carbon build-up before the start are fatal. To prevent this,
The water repellency of silicone on the insulator separates water and carbon from the insulator surface, preventing the plug's insulation from deteriorating.
● Housing end face chamfering
To improve resistance to abnormal combustion, the chamfering of the housing end face has been enlarged.
This also compensates for slight setting deviations.
In addition, it facilitates the discharge of residual gas and the influx of new gas, improving self-cleaning performance, making it a structure that is less prone to fouling.

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