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
