NGK is renowned as a world leader when it comes to spark plug technology and is also a pioneer when it comes to glow plug development. Niterra, the company behind the NGK and NTK brands has  been relentlessly developing engine pre-heating technology since the early 1960s and today offers a range of glow plugs which combines performance and efficiency with comprehensive market coverage. 

Glow plugs are essential to ensure a perfect engine start, especially in cold conditions. In colder weather more energy is required to help initiate ignition because both the intake air and the engine itself are colder and compression and pumping losses are higher. 

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 behaviour. 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.

NGK glow plugs deliver safe start-up from low ambient temperatures and low emissions during warm-up phase. They also offer stable idling running before the engine reaches operating temperature. The plugs have high-quality coating on the shell for high resistance to corrosion and the unique shell design provides excellent heat transfer, perfect gas-tight sealing, high shear torque, and high resistance to deformation and security of the heating coils

This all adds up to reliable cold starts, faster engine start-up and a long glow plug service life. 

NGK Glow Plugs are available from stockists nationwide.
