DENSO Iridium Racing Spark Plug IW01-24

【KITACO 025-021-0240000 DENSO Iridium Racing Plug IW01-24 KITACO 025-021-0240000】
"Iridium Racing" is a race-specific iridium plug that maximizes the performance of iridium.
● 0.8mm square all-platinum ground electrode
Compared to the nickel alloy conventionally used for spark plug ground electrodes, platinum has a higher melting point,
reducing the problems of the ground electrode melting or wearing out even under harsh racing conditions.
In addition, a 0.8mm square platinum alloy is welded and gap-formed without bending, resulting in no residual stress and improved durability. *Excludes RU01
● 0.4mm diameter ultra-fine iridium center electrode
By adopting the high-melting point "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
Small gaps have been provided all around 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 adhesion before starting are fatal. To prevent this,
the water repellency of silicone on the insulator causes moisture and carbon on the insulator surface to detach, preventing a decrease in plug insulation.
● Chamfering of housing end face
The chamfering of the housing end face has been enlarged to improve resistance to abnormal combustion.
This can cover slight setting deviations.
In addition, the discharge of residual gas and the influx of new gas become easier, improving self-cleaning performance and making the structure less prone to fouling.

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