DENSO Iridium Racing Plug IU01-27

【KITACO 025-025-0270000 DENSO Iridium Racing Spark Plug IU01-27 KITACO 025-025-0270000】
"Iridium Racing," a race-specific iridium spark plug that maximizes iridium's performance.
● 0.8mm Square All-Platinum Ground Electrode
Compared to the nickel alloy used in the ground electrodes of conventional spark plugs, platinum has a higher melting point, so
even under the harsh 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 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 jump 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. When the plug is fouled or carbon-coated, it burns off the carbon and restores insulation.
● Silicone Oil Coating
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 separate, preventing a decrease in the plug's insulation.
● Housing End Face Chamfering
The chamfering on the housing end face has been enlarged to improve resistance to abnormal combustion.
This also helps cover slight tuning deviations.
Furthermore, the discharge of residual gases and the influx of new gases are facilitated, improving self-cleaning performance and making it less prone to fouling.

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