3.5cc Glow plugs

We have tried all the plugs mentioned on this page and recommend them for racing. As a rule for high nitro 25-30% use a cold plug, for 10-15% use a medium and for no nitro use a hot plug. Remember if you experience premature plug failure check your engine head clearence. 20thou for 30% nitro. This should be about two-three head shims.
