ABOUT TURBO GLOW PLUGS
Turbo Glow Plugs where designed to give more performance to an engine, for the following reasons:
·It forms an uninterrupted combustion chamber.
·The advantage of better heat transfer or heat dissipation, and a leak proof seal, generated by the conical seat of the plug.
·Greater choice of thermal ranges, that allow for more precise tuning according to variations in weather conditions (temperature, humidity, altitude, barometric pressure, etc.).
The numbers and characters on the plugs, are the product number, wire thickness, and thermal range of the plug’s body. Example: The Novarossi C6TG (F) or (C)
§ Product: C (Conical)
§ Wire Thickness: 6
§ Plug Type: T (Turbo)
§ Plated: G (Gold)
§ Thermal Range: F (Fredda = Cold) C (Calda = Hot)
The plugs with cold thermal range F (Fredda), have a body with thinner walls and shorter body, so they dissipate heat better and faster to the engine head. The plugs with hot thermal range C (Calda), have a body with thicker walls and longer body, so they dissipate heat better and faster to the engine head. The number of threads is the same on both types of plugs.
How to select the proper plug:
·When the ambient temperature is high, we have to use a plug with thicker wire.
·With higher compression, we have to use a plug with thicker wire.
·Humidity determines if we use a Cold (F) thermal range, or Hot (C) thermal range.
·With high humidity percentage we should use a Hot (C) thermal range plug.
·If we have high temperature and high humidity, we should use a plug with thick wire and a Hot(C) thermal range.
The best instrument to determine which Turbo Plug to use, is those table digital weather stations, that have Temperature, Humidity, and some also Barometric Pressure on them. That is the key to success or failure tuning engines with Turbo Glow Plugs, because they are so sensitive to weather variations that is unbelievable.

I cant tell you difference between Standard,Standard Special and Standard Ultra i think the Ultra and special are the same just the ultra has gold plating i think the standard are for airplane and helicopter engines
