O.S. Engines LC3 Glow Plug

The O.S. Engines LC3 Glow Plug is a genuine replacement plug for compatible RC nitro engines using a standard-style glow plug. It is a practical choice for maintenance, break-in, everyday running, and keeping spares ready for race days or practice sessions.

A fresh glow plug can make a noticeable difference in starting, idle stability, throttle response, and tuning consistency. Replacing a weak or damaged plug early helps prevent wasted time chasing fuel-mixture issues that are actually ignition-related.
