The O.S. Engine RP6 Turbo glow plug is intended for model racers who require dependable ignition from compact, high RPM nitro motors. Its medium heat rating is suitable for .12, .15 and .21 engines fitted with turbo-type cylinder heads, helping sustain consistent combustion under race loads.
The RP6 differs from general-purpose plugs by addressing the specific thermal demands of turbo-head designs. This makes it a practical option when engines are run at elevated revs and ignition consistency is critical for lap-to-lap performance.
With a balanced heat characteristic, the RP6 supports good starting together with steady high-speed running. Its compatibility with common small engine sizes simplifies setup choices across a range of race engines.
