Production Description:

2L Subaru auto parts Denso Iridium Spark Plug IK20

DENSO Iridium Spark Plugs use the highest quality materials, and are produced in our state of the art manufacturing facilities.
Below is a cross-section of the highlights of the Iridium plug

The insulators are made of a highly purified alumina powder, which gives exceptional dielectric strength and thermal conductivity at high temperatures, as well as greater physical strength.

 

1.Insulator:The insulators are made of a highly purified alumina powder, which gives exceptional dielectric strength and thermal conductivity at high temperatures, as well as greater physical strength.

 

2.FIVE-Rib Design:The five-rib design prevents flashover and decreases voltage loss.

 

3.Copper-Glass Seal:A special mixture of copper and glass powder bonds the center electrode and insulator together for a gas tight seal. Proper heat is maintained and hot combustion gases are excluded.

 

4.Copper-Cored Center Electrode: A special center electrode incorporates copper into the core of the nickel chrome binary alloy. This gives superior thermal conductivity and increases the operating range.

 

U-Groove Ground Electrode:The originally patented U-Groove allows the spark to fill the gap formed by the U. This ball of fire develops a larger and hotter flash front so combustion is complete.

 

5.Patented Iridium Center Electrode:
Utilizes Iridium to create the world's smallest center electrode tip for maximum firing performance and reduced voltage requirements.

Tapered Cut: Improves firing performance by reducing quenching.

6.360°Laser Welding:DENSO perfected the Laser Welding Process, which provides a 360° seal so reliable the electrode resists wear even in the harshest conditions.

7.100% Pre-Fired:All DENSO spark plugs are pre-fired at the factory to assure highest possible quality.

Ultra Fine Electrode

By harnessing the power of Iridium, DENSO is suddenly able to shrink the surface area of the center electrode - the critical component of a spark plug. Unlike a typical platinum plug that has a 1.1mm diameter center electrode, DENSO Iridium Power plugs have the world's smallest center electrode measuring 0.4mm in diameter. This means that the voltage requirements are decreased while firing performance is greatly improved.

U-Groove Technology

Our patented U-Groove design changed the industry standard in the mid 1970s by providing a better design that virtually eliminates erratic starts caused by poor fuel mixture. The U-Groove results in less flame dissipation making the spread of the flame nucleus easier and therefore yielding greater firing energy. It gives the flame a groove to grow in, thereby creating a larger flame front for a complete combustion.

On a conventional plug, the flat electrode design crushes the spark, and the overall volume of the flash front is smaller.

The conventional method to improve firing was to increase the spark gap. This has a negative effect on the spark. With a U-Groove firing can be greatly improved without increasing the spark gap.
