*There is a specification of the stock plug cord which has no plug head terminal (4mm screw) as shown in the following figure for the spark plug. Please check the spark plug head before installation.Since brass plug head terminal is attached to our power plug cord, be sure to attach the plug head terminal to the spark plug head with pliers or the like before replacing the plug cord.
* The image is only for reference. The image shown may differ from the actual product.
Simply replace the power plug cord with an Ultra power plug cord to demonstrate the power increase
Ultra Silicone Power Plug Cord Features 1. Adopting highly conductive copper core wire.
2. By adopting the fixed winding resistance developed for each model, the maximum spark energy is uniformly supplied to each cylinder regardless of the length of the cord.
3.The winding resistors are located in the boots of both ends of the cord to efficiently eliminate noise at the source of the noise.
4. Ultra's unique caulking method and copper core wire provide outstanding tensile strength.
The use of pure silicon rubber provides excellent weather resistance and unparalleled voltage resistance characteristics, demonstrating durability that exceeds the life of the vehicle. etc., the ideal design structure is adopted.
Comparison with conventional products
・Conventional carbon cord The carbon cord, which is widely used at present, has a resistance value of 16kΩ per 1m. Therefore, there is a difference in the resistance value depending on the length of the cable, which means that the resistance value is different for each cylinder.Moreover, the spark energy of the carbon cord becomes weaker because the resistance value changes with age, and the deterioration of the rubber material accelerates, causing cracks and leaks.
・Ultra Silicone Power Plug Cord The flexibility of the copper multi-core wire makes it resistant to vibration fatigue and provides excellent durability over time.
◆Excellent strength is realized by adopting copper multi-core wire. 1. The combination of a 100% pure silicone rubber core and sheath provides the strongest voltage resistance characteristics.
2. Glass fiber braid is incorporated between the core and the sheath, and the mechanical strength is remarkably improved.
3. Tin-plated copper wire is used to eliminate corrosion and greatly improve tensile strength.
◆Impedance match and noise reduction The unique winding resistance efficiently cuts noise.Furthermore, the metal shield shuts out the noise around the spark plug, which is the root of the noise.(Metal shield is not available for DOHC engines, etc.) In addition, the resistance value of the conventional carbon cord type plug cord varies depending on the total length of the cable, The resistance value is constant for each cylinder regardless of the length of the plug cord, and it is uniform and draws the maximum current (from the ignition coil) to supply a strong spark.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
It arrived about two weeks after I ordered. I prefer less obvious colors to flashy ones, so Color:Gray. The length of the cord seemed to be quite generous, so I filled in the length myself. It's not the kind of parts where the performance difference can be experienced by everyone, but it's a proven brand, and the price is there, so I'm emotionally very satisfied.View Detail
Since I was able to confirm the leak from the Plug cord, I ordered MAJOR Ultra in the world of the four wheels anyway. The color of Plug cord is Red - You can choose either Gray. It was about 1 week for Production to order, but it arrived 4 days later. It will take time to replace Plug cord immediately. Ignition coil Remove the part which is the Screw part at the root, remove the cord, insert the new Plug cord deeply, just complete the Screw part and complete. In this case to note that the length is different for each Cylinder, because selecting the Plug cord together with the OEM and the positional relationship between each Cylinder and the Ignition coil are fixed, add the Cylinder number to the code mounting part of the Ignition coil Write etc. Devices are necessary so as not to make a mistake. In the case of ZXR 400, it is necessary to install the Brass terminal attached to the Plug Cord Set to the Plug. I think that it will not be a reference for comparison with the deteriorated Plug cord, but the engine start from Cranking got a little faster and Idling also stabilized.View Detail
