DENSO GE5-1 Iridium Saver (6081)

The GE5-1 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.

Specific details of this model include:

Thread Size: 14mm x 1.25
Reach: 19mm (3/4")
