hey knoxville here i have an ofna force .25 and i was wondering what glowplug i should use in this engine any info would be appreciated

Since the displacement is a little large, use a HOT plug. Of course, thats assuming that your using 20% nitro and nominal conditions.

ram

Probably a O.S. plug I heard those wear good.

Duratrax Silver Sport in my .25 and they work great and last a long time (Once the engine was broken-in)! Now that I have it broken-in I have gotten almost a gallon on one plug!
