O.S. Engine glow plug is ideal for 1/10 scale off road engines such as the Traxxas TRX2.5 and 3.3T engines and the O.S. .21 TMs. Like all O.S. Max glow plugs, the LC4 is tough enough to take the heat and provide hassle-free starts and outstanding durability. High-performance long reach glow plug suitable for 1/10 scale off-road applications that require constantly varying speed. The LC4's longer reach extends coil farther into the engine's combustion chamber improving combustion for better idling and good acceleration throughout the throttle range. Compatible with Traxxass EZ-Start system. Medium heat range for fuels with 10%-20% nitro content. No idle bar.

Requires: Glow plug wrench"
  • Traxxas T-Maxx Classic
