Technical specifications of turbo glowplugs
Turbo glowplug was conceived to give to the engine higher performance and it is available in 8 versions: 4 hot and 4 cold.You find here with a description schedule that gives to the drivers the possibility to choose the suitable glowplug according to the situation he is operating.

Merits and failings of turbo glowplugs
Hot glowplug guarantees a better adjusting of the engine at low RPM while the cold glowplug gives a better performance at high RPM. If you have a cold glowplug on your engine and have difficultes to keep it regular at low RPM, we advise you to make the base speed a little higher. In case the engine goes out again, we advise you to replace the above mentioned glowplug with a cold one; these difficulties in the carburation aren't due to a bad running-in of the engine but to anomalous climatic and meteorological conditions (see high degree of humidity, altitude, low pressure, etc...).
During the installation of a turbo glowplug on the under head verify that no dust or any other material come inside because they could make precarious the seal of this glowplug during the compression.
