GLOW PLUG NO.10 (A5)

O.S. has now introduced new Glow Plugs that are more suited to rigors of R/C Car Racing. Note that O.S. engine plugs are SHORT body plugs and should only be used in engines that require a short body plug. O.S. plugs should not be used in Novarossi, RB Concept and most other motors manufactured in Europe. Features: Increased durability (longer life span of plug) More reliable idle characteristics Smoother transitions from higher to lower RPM. Designed for constant "ON/OFF" throttle operations. This plug is suitable for 1/10 and 1/8 scale off-road racing. It has a slightly lower heat range than the O.S. #8. 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
