Spark Plug, Denso GK3-1A

Denso GK3-1A#4 Spark Plug for Industrial Engines: MAN, Cummins, John Deere, Liebherr, etc.

Item Description:

The GK3-1A Industrial Iridium Saver spark plug reduces maintenance costs by extending work life in high compression lean burn engines. This unique design guarantees high reliability for withstanding high combustion pressure by incorporating a stress resistant monolithic resistor that adheres to the resistor glass in the high temperature furnace.

1. 100% Pre-Fired: All Denso spark plugs are 100% pre-fired to assure the highest quality possible.
2. Copper-Glass Seal: Bonds the center electrode and insulator together for a gas-tight seal. Maintains proper heat and excludes hot combustion gases.
3. Five-Rib Design: Prevents flashover and decreases voltage loss.
4. Purified Alumina Powder Insulator: Provides exceptional dielectric strength and thermal conductivity allowing the material to stand up to extreme stress.
5. Removable terminal nut.
6. Platinum-alloy tipped fine wire ground electrode, with a platinum pad on the ground electrode and an Iridium pad without cross grooves on the center electrode.
