DENSO Iridium Racing Plug IU01-24

[KITACO 025-025-0240000 DENSO Iridium Racing Plug IU01-24 KITACO 025-025-0240000]
"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 the ground electrode in conventional spark plugs, platinum has a higher melting point, which reduces melting problems and wear of the ground electrode even under severe racing conditions.
In addition, a 0.8mm square platinum alloy is welded and gap-formed without bending, eliminating residual stress and improving durability. *Excludes 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 ignition voltage and significantly improves ignition performance. *Excludes 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 sooty, 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 insulator surface, preventing a decrease in plug insulation.
●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 deviations.
Furthermore, it facilitates the discharge of residual gas and the influx of new gas, improving self-cleaning performance and making it less prone to fouling.

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