NGK GLOW PLUGS
Glow Plug Technologies
Diesel engine glow plugs are basically differentiated between metal rod glow plugs and ceramic glow plugs. The two technologies have special characteristics in regard to thermal behavior. As many car manufacturers are not prepared to compromise on the quality and performance of their diesel glow plugs, they choose the proven NGK technology.
Safe start-up from low ambient temperatures
Low emissions during warm-up phase
Stable idling running before engine reaches operating temperature
High-quality coating on shell for high resistance to corrosion
Unique shell design for excellent heat transfer, perfect gas-tight sealing, high shear torque, and high resistance to deformation and security of the heating coils
Types of Glow Plugs
- Metal rod glow plugs
- Ceramic high-temperature glow plugs
