Denso GI3-5 Industrial Spark Plug
The GI3-5 Industrial Ultimate Durability Double Iridium Saver-DDI 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.
Specific details of this model include:
• Thread Size: 18mm x 1.5
• Reach: 20.6mm (13/16")
• Hex Size: 22.2mm (7/8")
• Gap: 0.3mm (.012")
• 100% Pre-Fired: All Denso spark plugs are 100% pre-fired to assure the highest quality possible.
• Copper-Glass Seal: Bonds the center electrode and insulator together for a gas-tight seal. Maintains proper heat and excludes hot combustion gases.
• Purified Alumina Powder Insulator: Provides exceptional dielectric strength and thermal conductivity allowing the material to stand up to extreme stress.
• Solid terminal nut.
• Platinum-alloy tipped fine wire ground electrode, with an Iridium pad on the ground electrode and an Iridium pad without cross grooves on the center electrode.
