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.

Forgot to say that the breaking point in choosing between C (long) or F (short) is humidity. Up to 70% use F type and above 70% use C type

can i get some help/opinon as to which motor would be best combined with Novarossi Turbo Tuned Pipe #52607?
NSR12S5
or
N12LL5
and also, seeing the performance specs of the two are pretty close to being similar in RPM, and HP. would the N12LL5 (long stroke) out perform the NSR12S5 (short stroke) in a tight track? lets just say they both have the same gear ratio.
any help would be appreciated.
Thanks!

I would say front 7 x 19 x 6 and rear 13 x 25.4 x 6 at a guess .. sorry i cant be more acurate, you may have to take them out and measure

may i ask if u guys always replace both front and rear bearings at the same time? also, all these while i have been using nova/max rear bearings, but for front, i use those other japan made bearings from bearing shop. will this combination cause my bearings to damage very often? overall, on weekend play, all my bearings lasted max. for 3months.

The 321PS has the now more common 'bigger' rear bearing. (all .21 PLUS engines for instance)
exact sizes dunno either.
