DENSO Iridium Racing Plug IW01-29

【Kitaco 025-021-0290000 DENSO Iridium Racing Plug IW01-29 Kitaco 025-021-0290000】
"Iridium Racing" is a race-specific iridium plug that maximizes the performance of iridium.
● 0.8mm square all-platinum ground electrode
Platinum has a higher melting point compared to the nickel alloy used for ground electrodes in conventional spark plugs.
This reduces issues and wear of the ground electrode melting even under severe racing conditions.
Additionally, 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 fouled or carbonized, 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 moisture and carbon from the insulator surface, preventing a drop in the plug's insulation performance.
● Housing end face chamfer
The chamfer on the housing end face has been enlarged to improve resistance to abnormal combustion.
This also covers slight setting discrepancies.
Furthermore, it facilitates the discharge of residual gases and the inflow of new gases, improving self-cleaning performance and making it 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.
