The manufacturer of the Denso GI3-1 6115 Iridium Saver spark plug uses the most modern finer grain ceramics with molded-in higher pressure. The higher density of the GI3-1's ceramics helps to prevent the insulator from electrical breakdown.

The Denso GI3-1 industrial spark plug also has better corrosion resistance thanks to special nickel plating.

These Denso industrial spark plugs have four small electrodes incorporated into them. These electrodes create a cross groove for improved sparking performance. innovation also suppresses voltage dispersion which provides for a reduction in required voltage.

The wear resistance of the GI3 spark plug is improved thanks to the high welding point of Denso's iridium alloy.

Denso industrial spark plugs reliably handle the most taxing engine conditions. The GI3-1 spark plug is manufactured with 360° laser welding that creates an incredibly tight seal. This seal prevents premature spark plug wear.

The Denso GI3-1 spark plug has resilient ignitability thanks to the 0.7mm center electrode.

For applications where high-reliability and the ability to endure high combustion pressures are required, the Denso 6115 GI3-1 is a clear choice. Denso incorporates a stress-resistant monolithic resistor which helps to eliminate high-energy coil interference and noise in electronic equipment.

The Denso GI3-1 industrial spark plug is extremely effective in bio-gas engines and offers world-class durability and performance thanks to the double iridium electrodes.
