The Denso GI3-3 6116 Iridium Saver spark plug is constructed with the most modern ceramics that have a finer-grain and are possess molded-in higher pressure. The higher density of the GI3-3's ceramics helps to prevent the insulator from electrical breakdown.

The Denso GI3-3 industrial spark plug also has better corrosion resistance thanks to special nickel plating.

Incorporated into this industrial spark plug are four small electrodes. 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 spark plug is improved thanks to the high welding point of Denso's iridium alloy.

The most taxing engine conditions are reliably handled by the spark plug. The GI3-3 is manufactured with 360° laser welding that creates an incredibly tight seal. This seal prevents premature spark plug wear.

The ignitability of these Denso spark plugs is resilient thanks to the 0.7mm center electrode.

For applications where high reliability and the ability to endure high combustion pressures are required, these Denso iridium spark plugs are 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 GI3-3 industrial spark plug is extremely effective in bio-gas engines and offers world-class durability and performance thanks to the double iridium electrodes.
