The finer the electrodes, the bigger the potential at the electrode tip and the stronger the electrical field, so the lower the required voltage. Therefore, reliable combustion is obtained over a wide range of running conditions from engine starting to acceleration.
Torch Iridium plug£¨3£©
¡ñ The electrodes have been taken to the limit of fineness, so the contact area with the flame core is small, the quenching effect is reduced, and the ignition performance is improved.
¡ñTorch Iridium plug can replace almost all normal spark plugs in China and overseas. When replacing normal spark plugs please check part number chart.
¡ñ For normal engines, replace with the same heat range as the spark plugs being replaced; for a changed engine, select spark plugs that
match the tuning level.
1 Sparks
Sparks discharge on the part of the electrode where they can spark most easily.
2 Formation of the flame core
The spark energy activates part of the air-fuel mixture and a small flame is produced.
3 Growth of the flame core
The flame grows even though energy is absorbed in the center and ground electrodes.
4 Ignition
Growth of the live coal vaccelerates and finally, the flame spreads as explosive
Iridium Power is recommended for the following kind of user.

¡°I want the next level of response and power for my baby¡±
For drivers that care about performance.

By using a 0.6mm diameter iridium alloy center electrode and a special ground electrode, Torch Iridium plug realizes spark performance unseen until now. It steadily gives a high level of response under a variety of driving conditions. The result? Increased acceleration and torque compared to regular plugs.

¡°It¡¯s the car that I drive every day, so I want less fuel consumption.¡±
For drivers that care about mileage.
If you use your car on a daily basis, you may be concerned about fuel consumption. Torch Iridium plug is one solution.

Improved Horse Power(1)

Get more power with an optimal combustion cycle.
Torch Iridium plug has a low required voltage and a high ignitability, resulting in less misfiring, the outcome being a dramatic improvement in combustion. Engine output is thus increased. The findings of a bench test using a motorcycle engine to show the improved combustion from Torch Iridium plug is shown on the below. Compared to normal plugs, a 0.5ps (1.4%) improvement is seen in output at 110km/h.


Improved Acceleration
increased response and acceleration performance.
Torch Iridium plug best demonstrates its performance improvement during acceleration. Torch Iridium plug has a 0.6 mm diameter iridium center electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.


Improved Horse Power(2)
The 0.6mm center electrode increases output under various driving conditions.
The power produced by the 0.6mm dia. iridium center electrode is Torch Iridium plug unmatched by other plugs. The graph below compares the resulting power when Torch Iridium plug is installed compared to other high performance plugs. Using a 0.6mm dia. fine center electrode, there is more power compared to 0.8mm and 2.5mm dia. plugs. This is what makes the difference in acceleration and in your lap time.

Improved Fuel Mileage
Why Iridium Plug Has so many Advantages?
Plug electrodes conventionally have used nickel and platinum. These were not pure metals, but alloys containing other metals. Depending on the composition of the alloy, the matrix material's properties can be maximized. Using the same approach, iridium is alloyed with platinum and palladium, which helps iridium to get even better comprehensive performance. TORCH was able to make diameter of the iridium 0.6mm.
The most important things for plug performance are ignitability and sparkability. TORCH has succeeded in commercializing the 0.6mm diameter center electrode plug.
The finer the electrode, the more concentrated the electrical potential and the stronger the electrical field strength becomes, leading to a lower required voltage. This results in a steady combustion in a variety of driving conditions, and better starting and acceleration for the engine.
Specifications Include Terminal


A terminal nut is attached that fits with most of the world's spark plug cables. Please remove the nut for installations that do not require one. Spark plug with solid terminal nut cannot be removed.
Built-in, Highly Reliable Resistor
All Torch Iridium plug plugs include a highly reliable, 5,000 ohm resistor specification to reduce electromagnetic noise that may affect electronic devices. (For all plug types)
Highly Corrosion Resistant Nickel Plating
The plug housing is plated with evenly-covered nickel It is highly resistant to corrosion and rust even in high humidity climate
Projected Center Electrode
In order to improve ignitability, the center electrode protrudes more than with conventional type plugs This improves both acceleration response time and performance
Taper-cut Ground Electrode
The tip of the ground electrode is cut to a fine taper to reduce the adverse effects of quenching, which greatly improves fuel ignitability. Also, because of the streamlined, taper-cut shape, the fuel-air mixture spreads more evenly in the gap, resulting in steady, reliable igniting of combustion.
Insulator Projection
The projection of the insulator is optimally designed based on each plug's thermal value. This corresponds to requirements unique to thermal value, such as self-cleaning ability at lower thermal values, and heat resistance at higher thermal values. (For all plug types)
0.6 mm Diameter Iridium Center Electrode
Using a new iridium alloy with a very high melting point, the tip of the electrode can be made very fine. This enables the reduction of voltage necessary to cause the spark, and greatly improves ignitability. Moreover, the special iridium alloy used was specially developed by TORCH.
360¡ã Laser Welding
The process used to mount the iridium tip is a highly reliable process combined with resistor welding and "All-around Laser Welding" that is able to withstand all kinds of driving conditions. (For all plug types)
