Which Traxxas plug should I use in my TRX engine? What is the difference between the three plugs?
Traxxas glow plugs are the only plugs we recommend you run in your Pro .15, TRX 2.5 or TRX 3.3 Racing Engine. The standard long hot plug (part 3230) is the replacement plug for the Pro .15 engine. In hot weather use a medium plug in the Pro .15. The super duty long plugs (medium #3232 and medium 3232X) are the replacement plugs for the TRX 2.5 and TRX 3.3 engines. Either will work equally well in your engine.
