●Detailed specifications have been changed to match the characteristics of iridium plugs, and the blue color has been further refined.
Silicone cables, boots, and caps are all made of silicone rubber with excellent voltage and heat resistance properties, and are unified in the "cobalt blue" color that made the name Ultra Silicone Cord so popular.
The core wire uses a copper core wire with the best conductivity, and like the conventional silicone series, it has a three-layer structure of a silicone core, glass sheath, and silicone rubber coating, and has a withstand voltage of 150,000V. Achieving high voltage resistance.
We have adopted a low resistance value that matches the latest spark plug characteristics, and each cylinder has a uniform resistance value of 0.5KΩ (less than 1/2 of our conventional product). ) was developed and adopted.
Although the resistance value is as low as 0.5kΩ, the wire-wound noise suppressor (resistance) efficiently cuts noise due to the effect of the L (inductance) component.
Also, by placing Ultra's unique noise suppressor at the end of the plug cord, a uniform resistance value is achieved for each cylinder, and by adopting a low resistance value of 0.5kΩ, maximum spark energy is supplied without loss. To do.

●Please check the ULTRA homepage for details and compatibility.

●What has changed is not only the cable color, but also its performance As well as its presence as a part of the engine room, the tireless pursuit of performance and deep commitment have been condensed into this product. Ultra wants to give shape to the performance that tuners and drivers demand from their ignition systems. It is also known as a synonym for silicone cords such as ultra red and cobalt blue, and its original technology, such as the method of placing a unique wire-wound noise suppressor in each terminal, is a manifestation of this commitment. Ultra will continue to create products that customers can be proud to call their ``Best Buys'' and that are made with particular attention to detail.
