See the O.S. glow plug chart below to compare the different short body standard glow plugs available for O.S. engines:

Model	Heat Range	Description
No.6	Hot	Formerly known as the OS A3 plug. This hot plug will provide a more stable idle and crisp acceleration when compared to a cold plug. This plug is recommended for low nitro content fuels and .12 class engines.
No.7	Medium Hot	Slightly "hotter" than the #8 and ideal for the constant "on/off" throttle action in 1/10 and 1/8 scale racing.
No.8	Medium	A medium heat range plug for 1/8 scale racing and most .12-21 car, boat and truck engines.
No.10	Cold	Formerly known as the OS A5 plug. This is now rated as a cold plug and is recommended for high nitro content fuel. This cold plug will produce the most power, but will provide a less stable idle and a narrow tuning window
