A hot plug will ignite the mixture sooner and so advance the timing for low end power while a cold plug the opposite. In hot weather the air is thinner and so you dont get the pressure in the engine to ignite the mixture as soon as when its cold. You can run a hotter plug to compensate.

So.... Hot weather = Hot plug. Cold weather = cold plug

I wonder why, when i run my car during night time. It runs perfect when im using very cold plug during night and the other day we run again day time my car wont run that good as night time. Maybe thats the reason why i run like that bec. I didnt change the plug everytime run (I use plug same day & night) lol. Salamat bro

Night Time is cooler = denser air = more oxygen = leaner air mixture and more effective cooling.

All equaling more power. Engines love cool air.

All plugs are different. If your asking for which heat range is best , then someone already answered that. Not sure if its correct but otherwise I find glow-plugs you just gotta play with and see the results for yourself.

Mainly what you have at your lhs is what you get to choose from and you go from there. I do order some plugs but only for specific reasons and or when I found a plug I personally like.

Plugs are just like fuel and anything else. Its what you can get and what you like , what runs well with your motor etc.

I believ longer glowplugs are for turbo engines. According to what I have read, do NOT use a turbo glow plugs in a non-turbo motor and vise versa. This could cause serious damage

think of plugs as a way to tune a motor , hot plugs tend to advance
the timeing, cold ones less so, .12 tend to run best with hot ones
.21 best with medium to cold, short twisty tracks hotter plugs
long hi speed tracks cold , hot plugs need a little richer setting
with cold plugs a little bit more forgiving when you lean the motor out

Long body has move volume inside the plug so retards the timing slightly. It makes the plug slightly colder hence the name on the novarossi plugs

C6TGF is a 6 wire plug with a long body (Freddo for cold in Italian)
C6TGC is a 6 wire plug with a short body (Caldo for hot in Italian)

I always use the Cs
